brain) 2. What is the advantage of having a cerebrum that is highly convoluted? What term is used to indicate its crooves? Its outward folds? What groove divides the crebrum into two hemispheres? What divides the parietal from the frontal lobe? The parietal from the temporal lobe? Convoluted cerebrum allows more neurons to occupy the limited space ridges are called gyri shallow grooves are called sulci and deeper grooves are called fissures

Abnormal activity in temporal lobes is usually due to past head trauma‚ infections‚ lack of oxygen‚ exposure to toxins‚ or can be inherited. SPECT findings‚ decreased activity in the temporal lobes‚ and at times excessive increased activity. Even though the six types have some commonality of symptoms‚ each type has its own set of symptoms and specific treatments

After all the tests were done‚ the psychologist concluded that he had a dysfunctional frontal lobe. The frontal lobe helps humans stop impulse and violence. With his frontal lobe not working his thought process was different from

This essay is going to demonstrate knowledge of neurotransmitters dopamine and show evidence to how it is a factor that influences behaviour of those who have high and low levels of dopamine in their system. This essay also looks into the theory of multiple motivations: hierarchy of needs and shows the relevance motivation has to dopamine. Variety of articles shows how dopamine is an influence on mental disorders such as psychopathic behaviours. Neurotransmitters are neurons that create a specialised

Tutorial: The Brain The brain was a mystery for a very long time. Modern imaging has allowed us to study the brain and locate where important functions are occurring. Please remember that the functions do not happen in just one area of the brain. Many neural layers and areas are found in any one activity that happens. But what we do know though is that some areas do appear to be predominantly involved in certain functions. We will learn about the brain in the three-part model. We’ll first look at

weights approximately 35-40 grams and is around 43 cm long in adult woman and 45 cm long in adult men. The frontal lobe of the brain controls our judgement and is responsible for reasoning‚ planning and carrying out complex tasks. The frontal lobe works together with the amygdala. This is the part of the brain which is linked with emotional memory. The prefrontal cortex (part of the frontal lobe) analyses a situation‚ such as a student about to walk into an exam hall to take an important exam‚ and if

In a study conducted at Boston’s McLean Hospital‚ psychologist Dr. D Yurgelun-Todd and colleagues placed teenagers inside of an MRI machine. In this study of the Frontal lobes (the seat of goal-oriented rational thinking) some teens (who were in between the ages of 11 and 17) were compared to a group of adults. In the study they were shown pictures of people who displayed the emotion fear on their faces. The younger
