Abstract
In the last decade scientists have made huge progress in the neuroscience field, which has had a tremendous impact on leadership development studies. Knowledge gained through brain observation helps us to understand how the brain responds during certain activities and how some processes in the brain are connected to each other. One important part of our brain is the limbic system, a primitive system responsible for our long term memory, how we build relationships, and how we create patterns based on experiences. Another important part is the prefrontal cortex, which is evolutionarily younger than the limbic system and responsible for more sophisticated processes in our brain, such as our working memory with which we plan, react and judge. Connection between the limbic system and the prefrontal cortex determines our response to certain situations. If we know that the brain cannot use both with the same power in certain situations, and that our brain is plastic and has the ability to change if influenced by certain exercises, this could be very useful information for leaders. We can use this knowledge to improve many fields from how to build empathy to how to change our and others’ behavior in accordance to make better organization, which will consequently make us better leaders.

Neuroscience Leadership
Leadership is probably as old as humanity. As a matter of fact, we can find some sort of leadership also in the animals, especially those who live in groups. We all heard of wolves and their authoritative organization. However, humans are in higher, more complex levels of organizational behavior that gives us special purpose and a role in society. That requires those with leadership responsibilities to have special abilities to fulfill their role and be successful leaders. Because of today’s world where leaders are not necessarily “natural born”, we cannot expect that everybody who leads others will have certain abilities to do that successfully. That’s the reason we invented leadership studies, which can help us develop leadership skills. As in any other studies, progress is made in the leadership field as well, and the biggest progress was made in the last decade when we figured out how to use neuroscience knowledge to affect leadership skills. Neuroscience can help us be a better leader, and consequently we’ll have better, more successful organizations. The things neuroscience noticed about the brain in the last decade are not new, they are always been there, we just discovered them now, explains Pearce in the interview (Pearce, 2010). Basically, what we are learning is how the brain works given certain stimuli. According to that fact, we can now tweak certain messages in order to get a desirable response. In Pearce’s opinion (2010), the most promising field for leadership is the empathy field, more accurately how empathy is actually developed. It’s very important how we build up a capability of understanding how other people feel or think. Now we know when we have a conversation with others we are actually building a model just as though we are having their response, which is most easily seen in babies, how they learn through imitation, when the mother is smiling the babies’ brain creates a pattern that is exactly the same as if the baby were smiling itself (Pearce, 2010).
Understanding others how to think and feel is probably the most important area we can improve with neuroscience; the second most important is understanding implicit memory versus explicit memory. Both forms of memories are types of long term memory, which is more complex than short term memory because it stores different types of information such as procedures, language, life experiences, etc. Explicit memory or declarative memory requires conscious thought while implicit memory does not require conscious thought, but allows you to do things by rote (Types of Memory).
Long term memory is formatted by the limbic system, in particular the hippocampus and amygdala, and the whole limbic system governs emotions and behavior (Jasmin, 2012). The limbic system is part of our brain through which we develop our relationships. The limbic system also creates implicit patterns for us that we remember, so every experience we have is a reflection of experience we’ve already had, which means that we see that pattern first rather than see the reality. Understanding how preconception drives most of our human behavior is an important part of leadership because it can help us to look in implicit memory and develop ways of communicating and give people an opportunity to not react with their typical response, advocates Pearce (2010)
Another important role in our brain is carried by prefrontal cortex located just behind the forehead. The prefrontal cortex is evolutionarily younger than the limbic system and as Dr. Swenson explains (as cited in Steadman, 2011, p. 2), is the place where more sophisticated processes of mind occur and actively influence body function and performance. The prefrontal cortex is also known as the working brain, because it manages memory, planning, mood, personality, reactivity to surroundings, sequence of activity, judgment, etc. With the prefrontal cortex we solve math problems, develop abstract concepts and ponder our own existence.
Therefore, every part of the brain has its own role and is running more than other parts of the brain in certain events or actions, which Steadman (2011) describes by citing numerous authors (p. 3). Every part of the brain is using for its functioning certain amount of blood that provides the oxygen needed. The brain manages this blood need to redirect it to certain areas of the brain that are more in use at a certain time event (e.g. visual cortex, motor cortex). That necessarily leaves less fuel for other brain function, which means that when the limbic system is engaged (during high thread stress) the prefrontal cortex will lack fuel, this handicapping a person’s ability to use cognitive processes in that situation. Rock explains in his book Your Brain at Work, “the degree of activation of the limbic system is the degree of deactivation of the prefrontal cortex” (as cited in Steadman, 2011, p. 3). This fact tells us that in critical situations, our emotions suppress our rational thoughts, which is bad for leaders who want to preserve cognitive function during stressful situations.
This basic knowledge about the brain is necessary for leaders because they can be aware of functions in their brains, and that they are able to train their brain to respond differently than how nature wants to respond, because the limbic system is a primitively old system developed to respond to life-threatening situations, it still has authority over brains (Steadman, 2011, p. 3). According to Rock (2009): “People who succeed under pressure have learned to be in a place of high arousal, but maintain a quiet mind, so that they can still think clearly. Over time and with practice this capacity can become an automatic recourse" (p. 115). Knowing this fact and having awareness that a leader needs to keep his head cold as much as possible during stressful situations is crucial to the outcome of any kind of mission, just imagine the military leader who will react all the time under the run-fight mode instead of using his cognitive mind to face all the situations on the battlefield.
Steadman explains in his article Neuroscience for Combat Leaders that platoon leader and platoon sergeant are the first leaders who are engaged in more complex problem solving rather just focusing on the direct fire battle. The more moving up through the ranks, the more leaders are under cognitive region, so they have to learn how to decrease the effects of stress. This can be done in multiple ways, which mostly deal with breathing and visualization (Steadman, 2011, p. 4-5). But a leader has to do much more than just care for himself; he also must be aware that he is responsible for people who need to be led and that the organization’s success depends on how they will perform as a group. A leader has to enforce these techniques to his subordinates; one way to do this is proper training for their job, either for combat or another profession a leader works in. Training in repeated activity, which are battle drills in the military meaning, certainly can literally “change cellular structure and strength of connection between neurons” (Steadman, 2011, p. 9). Doing these under stress will prime the individual to control stress and become able to work with emotional control. Another important thing is how people feel in the team, which requires the leader to understand social aspects of the brain. The brain has a social network responsible for all social interactions and helps individuals to understand and connect with others. Rock says: “Studies show that the strongest emotion in a team can ripple out and drive everyone to resonate with the same emotion, without anyone consciously knowing this is happening” (2009, p. 161).

For all leaders it is also important to strengthen their cognitive memory, which is achievable with building their own database that will assist them using that knowledge during stressful situations. This is doable by studying certain doctrine and history, recording and discussing new ideas, rehearsals, etc. All this solid knowledge is a part of long term memory that will provide the prefrontal cortex with a vast array of options from which it is possible to generate new solutions (Steadman, 2011, p. 9-10).
The brain approach leadership offers us even more than stated above: Researchers are developing exercises that will allow individuals to alter their brain activity and consequently will become better leaders, and proof of that are a huge number of internet sites offering us brain training exercises. The concept of neuroscience leadership has been proven, now we have to go to operationalization, says Professor Balthazard from W. P. Carey School of Business (Using Neuroscience to Learn How To Build a Better Leader, 2011).
One might object here that neuroscientists do not take a holistic approach to human personality and that the brain is not a separate part of a person. That kind of counter argument comes mostly from philosophers saying that neuroscientists incorrectly attribute certain abilities to human brains because of misunderstanding what constitutes a person (Colborne, 2012). They go even further arguing that neuroscientists use impropriate language describing the brain as if were a person itself, like saying that car drives and bicycle rides. And I could even agree with that to some point, but taking out the parts from the whole isn’t really wise not even from their perspective. Neuroscience is not an independent field; it is just a tool to help other sciences to fulfill its research, so we can use it successfully only if we have certain knowledge about philosophy, psychology, leadership, sociology and life generally.
Probably the most important thing we want to accomplish concerning common society is to have success in any kind of organization, because history and experiences teaches us that a group of people could accomplish more than only one person can. Just take for example a military organization, which is very complex and made from a lot of parts. And that kind of system that includes more people needs someone who is moving these parts. That’s why leadership is a very important field that consists of many other studies, and now we can be more confident adding another field called Neuroscience. Using neuroscience itself is the same as wanting to use any other science solving multidisciplinary issues; it just doesn’t work, but using neuroscience as one of the tools, is certainly a multiplayer in the leadership field.

...Name: Mandique, Ynicia Rancy M. Date: August 20, 2012. Thinking About Thinking: Analytical, Creative, and Practical Questions: 1. Describe some of the evidence regarding the phenomena of priming and preconscious perception. Answer: Priming does not have to be visual. Priming effects ca ne demonstrated using aural material as well. Experiments exploring auditory priming reveal the same behavioral effects as visual priming. Using neuroimaging methods, investigators have discovered that similar brain areas are involved in both types of priming. 2. Why are habituation and dishabituation of particular interest to cognitive psychology? Answer: Dishabituation is the recovery of responding to a change in the environment (e.g., you may no longer wake to the sound of traffic outside your room, but if an accident occurs outside your window you'll likely get up). Habituation and dishabituation allow researchers to assess how much the infant understands about her/his world. Recall that habituation is a very simple type of learning that refers to the gradual reduction in the strength of a response due to repetition (e.g., after a few sleepless nights of living near a busy intersection, you probably will no longer wake up to noisy traffic). 3.

Fluidity of Nueroscience

...The Fluidity of Neuroscience Gender Norms & Racial Bias in the Study of the Modern "Neuroscience" Neuroscience is the scientific study of the nervous system. Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. The scope of neuroscience has broadened to include different approaches used to study the molecular, cellular, developmental, structural, functional, evolutionary, computational, and medical aspects of the nervous system. The techniques used by neuroscientists have also expanded enormously, from molecular and cellular studies of individual nerve cells to imaging of sensory and motor tasks in the brain. Recent theoretical advances in neuroscience have also been aided by the study of neural networks. Given the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators. For example, the International Brain Research Organization was founded in 1960, the International......

Perceptions of Brain Based Learning

...Running Head: PERCEPTIONS OF BRAIN-BASED LEARNING 2 Brain-based learning theory has devised a new discipline known by some as educational neuroscience, or by others as mind, brain, and education science (Duman, 2010). It is a broad and comprehensive approach to instruction using current research from neuroscience. Brain-based education emphasizes the manner in which the brain learns naturally and is based on what is currently known about the structure and function of the human brain. This theory is a concept that includes an eclectic mix of teaching techniques. BBL practices call for teachers to connect learning to students’ real lives and emotional experiences, as well as combining strategies like problem based and mastery learning and considers learning styles of individual students. Opponents of brain-based learning strategies argue that neuroscience alone cannot provide usable knowledge that translates into positive teaching strategies (Clement & Lovat, 2008). However, teachers and researchers who are implementing, and testing BBL strategies, contend that a working knowledge of neural functioning is paramount as educators look for successful ways to address individual learning needs. Balil Duman ((2010) shares that several educators and brain researchers have conducted and produced research that reveals that individuals learn in different ways thus multi-dimensional teaching models should be used to transmit information to students.

Neuroscience Is the Study of the Human Nervous

...Neuroscience is the study of the human nervous system, the brain, and the biological basis of consciousness, perception, memory, and learning. The nervous system and the brain are the physical foundation of the human learning process. Each of our brain cells can grow up to 20 dendrites, which store millions of pieces of information. These dendrites also affect our acquisition and loss of behaviors. Neuroscience links our observations about cognitive behavior with the actual physical processes that support such behavior. It is currently theorized that the cortex of the human brain is made up of two sides: the left "scholastic brain"; and the right "creative brain". Each side is joined by a corpus callous which sends millions of messages between the left and right sides. The more you use both sides together, the easier it is to learn. These messages make up the construct we call learning, and when engaging in reading, a students' brain uses both sides. Counselors who can find a way to stimulate these cortexes can help facilitate Therapy in clients. Cognitive neuroscience is a relatively new field of research, and as it is further explored, more educational implications of this field will certainly develop. At its most basic, learning is the process of acquiring memory, but complex neurological processes must take place to transfer newly acquired information to the long-term memory bank, where it can be stored for later use in novel ways. The brain actually has multiple memory......

...1. Why are MeCP2 mutations always sporadic rather than hereditary? (2 marks) The mutations of the MeCP2 gene are sporadic rather than hereditary because a female child with Rett syndrome will usually die at a very young age, however, if they also have a normal gene they may live longer but no family history has been found to be connected to RTT. The rare male who has RTT will die before or shortly after birth; therefore this disorder cannot be hereditary. Add notes from last weeks lecture 2. Contrast the genetic cause of Rett syndrome as compared to schizophrenia. Explain your answer in general terms, address the relative involvement of genes and environment. RTT is caused by the lack of expression of MeCP2 and is sporadic. There is some evidence that schizophrenia is hereditary, and researchers have only established a few gene candidates for its cause. Another difference between RTT and schizophrenia is that RTT has an has a specific etiology, whereas schizophrenia receives a psychological diagnosis. If an individual is exposed to a mutation of the MeCP2 gene leading to RTT, they will develop this syndrome regardless of positive or negative environmental influences, on the other hand, schizophrenia appears highly influenced by environment, including stress, poor family environment and the use of marijuana. Several susceptibility genes have been indicated that may interact with environmental influences to produce schizophrenia. Add notes from last weeks......

...Initial Market Reaction to the Deal After the deal announcement on July 28th, 1993, the market obviously reacted to both side of the acquisition. Merck Side At the announcement of the deal, the stock price of Merck fell from $17.39 to $13.06 (see graph below). At the time, the deal was not supposed to be easily digested by Merck investors. The main reason for this market reaction was the risk of antitrust review. With $9.7 billion in 1992 revenues, Merck has about 10% of the fragmented American drug market. Medco, with $1.8 billion in sales in the fiscal year that ended June 30, 1992, has about half of the mail-order drug business and 22% of those eligible for employer-financed drug benefits. Medco indeed virtually counted every major drugmaker among its suppliers, among which several were likely to object to Merck’s influence, as a matter of conflict of interest. Even if that matter would be cleared up by Merck, some of its competitors privately already took the decision to drop or cut back their dealings with Medco in case the deal was settled and thus look for alternative retailers, either as clients or as potential targets to perform vertical integration. As Wygod (Medco’s Chairman at the time) said, “some manufacturers are going to look at this as a strong competitive move, and they will perhaps tie up with other pharmacy management companies." Moreover, drug industry specialists insisted on the fact that the customer base of Medco would not be......

...background of Neuroscience has encouraged me to pursue a degree in this field. The debate between the schools of philosophy and neuroscience is exceptionally interesting as it has opened up an awareness of what it means to be human. Difficulties in describing the conscience using natural sciences is perhaps the most heated of debates and research into neurotheology such as the existence of the ‘god spot’ shows how vast the subject is. The subject encompasses many of the life sciences and would allow me to gain knowledge of several different disciplines. Combining knowledge of physiology from biology and with the structure of substances learnt in chemistry provides me the rigorous scientific background that is crucial in the neuroscience course. My understanding of molecules and chemical concepts developed in ‘A’ Level Chemistry will prepare me for this degree as the same knowledge can be applied to understand how simple neurotransmitters can impact on human behaviour. In class, we undertook a module called “What’s in a medicine?” where we learnt about the importance of medicines in curing diseases. This entire unit focuses on the mechanisms of action and the clinical significance of drugs such as aspirin or penicillin.

Behavioural Neuroscience

...BACKGROUND Biological psychology, also known as behavioral neuroscience, is defined as the application of the principles of biology to the study of physiological, genetic, and developmental mechanisms of behavior in human and non-human animals. It usually looks in at the level of nerves, neurotransmitters, brain circuitry, and the basic biological processes that run hand in hand with the body's normal and abnormal instincts. Most of the time, experiments in this field of work involve non-human animal models such as rats, mice, and primates which contributes to evidence-based practice, which i suppose is somewhat rare in the general title of psychology. Biological psychology also has a strong history of contributing to the understanding of medical disorders including those that fall under the category of clinical psychology, and abnormal psychology. This certain field has contributed important therapeutic data on a variety of conditions such as parkinson's disease, huntington's disease, alzheimer's disease, clinical depression, schizophrenia, autism, and anxiety. CAREER INFORMATION: Studies in genetics, depth psychology, sociology, or environmental science may all contribute to a fundamental preparation of the field. Those hoping to enter the career should begin training at the undergraduate level, pursuing an associates or bachelors degree in any number of related fields, including biology, chemistry, physics, psychology, or pre med. Graduates of these programs may find...
