1 Introduction

==============

No single theory has managed to comprehensively explain front lobe

functionality. Many theories exist that explain frontal lobe

functionality, which focus on various aspects of functionality such as

planning and ability to moderate behaviour, social behaviour,

personality and emotion. The frontal lobes are complex in their

functionality and only a synthesis of the various theories can begin

to present a more adequate picture of the various functions of the

frontal lobe, as well the importance of the various other parts of the

brain that are inextricably intertwined with the frontal lobes in

their functionality. “It is clear that every complex form of behavi...

    The prefrontal cortex (PFC) also controls behaviors that depend on context (Kalat 2004). For example, if my cell phone rings when I am at the mall or grocery store I would answer it. If it rings while I am at the movies or in class I wouldn't answer it. People with frontal lobe damage often exhibit inappropriate behaviors due to the inability to recognize context. Other studies indicate that the PFC is also responsible for regulating emotions and decision-making.

  • The Many Functions of The Brain

    1248 Words  | 3 Pages

    The brain has many functions in which it helps process and understands information. One aspect of the brain is its memory. Memory is there so information can be used to understand what is happening around someone. The function of memory is somewhat of an enigma to many scientists. How does the brain store and retrieve such information and at such high speeds? Although it is hard to conceive the actual machine working behind memory scientist have been able to figure out the physiology behind this process. The brain is composed of millions of neurons. Communication between these neurons is by using nerve impulses from the axon of one neuron to the dendrites of another. This is called a synapse. All impulses are transmitted by a chemical substance, which is called a neurotransmitter. Scientists have not been able to explain the actual processes that occur within memory. They cannot explain why people can remember something's and not other or why some learning strategies are better then others. It turns into more of a guessing game using analogies to explain what happens. Memory has been compared to the way " we rummage our house for a lost object." That is the way the brain works in terms of memory. The confusing part is how one can store it retrieving it and even use it to decipher harder more complex problems. In one early theory memory is broken down into two areas. These areas are primary memory and secondary memory. Primary memory is said to not have to be retrieved. It was never lost and it is what is seen in present time. Secondary memory is a place where everything can be stored, but the difference is secondary memory has to be retrieved and cannot be used like primary me...

  • The Human Brain: The Perception Of The Brain

    928 Words  | 2 Pages

    In the world of man, one would think everyone sees the world in the same way. That person would be greatly mistaken. The human brain is more complex than most can believe; some would say the brain is still a modern mystery. When it comes to psychology, the idea behind perception and cognition is usually through the psyche of a ‘normal’ individual. However, some argue that studying abnormal brains, or persons with brain disorders could help better understand perception and cognition. It is correct that unusual brains can perceive differently from a standard brain. These studies can only help the scientific field expand its understanding of the brain by encompassing all brains, including those suffering from disorders. In short, brain disorders

    Stuss and colleagues (2002) argue that clinical neuropsychology at its simplest is “the understanding of brain-behaviour links and their applications to clinical situations”. In their review of the history of clinical neuropsychology, they speak of three fields that have contributed to our current understanding of brain behaviour links including 1) behavioural neurology, 2) neuropsychiatry and 3) clinical neuropsychology. Within these disciplines, a range of techniques are used to investigate loca...

    Shawn T. Smith’s “The User’s Guide to the Human Mind” shows the way the brain reacts and the reason it reacts to certain events, tendencies, and otherwise work against us in functional pursuits. It helps us to understand why we develop anxiety and depression. He suggests us struggling against unhappy anxious thoughts and make friends with our minds. Smith states “your mind is not supposed to make you happy it’s supposed to help you survive.” The brain has bad habits one is avoiding new experiences two is our brain looks for problems that don’t exist. Smith states that the mind is built in such a way that most of its functions and drives lie outside our control.

    The brain is an astonishing product of evolution. This can be seen by our numerous technological developments and society structure. The brain has always been the most important organ for species that had developed past the cellular stage and has always performed the same functions that it does now but has developed constantly to where it is now through growth and a reorganization of its’ primary functions and gained the ability to learn has been something that the human brain does better than other brains. Our brains have not always been like this and many social and biological factors have led us to where they are now.
