Unit 3: Biological Bases of Behavior 3B: The Brain 1. Lesion- Tissue destruction; a brain lesion is a naturally or experimentally caused destruction of brain tissue. 2. Electroencephalogram (EEG)- An amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by electrodes placed on the scalp. 3. Computed Tomography (CT)- Series of X-ray photographs taken from different angles and combined by computer into a compsite representation

Mind and Brain - Is There a Difference? Lisa Fitzsimons PHI 200 Instructor Brianne Larsen 02/20/2012 The brain is the most complex organ of the human body; scientists still have many unanswered questions about it. One question is are the mind and the brain the same entity or are they separate entities within a person’s head? It is undisputed that the actions of the mind are within the brain. But are the actions of the mind only neurological impulses sent between neurons within the brain

thought--what causes a person to act so violently? There have been many studies done to try and find an answer. For a crime such as serial killing‚ there are two thoughts. The first idea is that serial killing is caused by an abnormality in the frontal lobe of the brain. The other is that serial killers are bred by circumstance which means they have certain genes that make them prone to becoming a killer. With some analysis‚ the evidence for both theories can serve to prove that serial killers are

The size of the brain in both male and female are different‚ males are said to have larger brain than the female. Thou in females the frontal lobe is larger‚ frontal lobe is used for problem solving and decision making .In males the parietal cortex is larger‚ the function of this space perception and regulation of sexual for social behavior. Woman’s brain have tighter packed neurons which explains

However‚ psychologists’ continue to study his brain and the effects of his injury and its role in cognitive functions years later. Phineas Gage was a foreman at a railroad who suffered damage to his prefrontal lobes as a result of an accidental explosion in the year 1848. This explosion caused an iron bar about a meter

The parts of the brain that are affected by Alzheimer ’s Diseases is the frontal lobe‚ the temporal lobe‚ and the parietal lobe. The changes that occur leads to nerve cell death and tissue loss throughout the brain. Then over time the brain will shrink dramatically‚ affecting nearly every function or part.

Each of the hemispheres are divided into four lobes. Frontal‚ parietal‚ occipital and temporal are the four lobes. The forebrain controls cognitive functioning. The cognitive functions are: sensory and motor function‚ temperature regulating‚ reproductive‚ eating‚ sleeping‚ and displays emotions. In 1848 an unforeseen accident

in most cases‚ this deficit cannot be attributed to elementary motor or sensory systems. Alan Sunderland et al‚ states that the presence of apraxia is largely attributed to the left hemisphere of the brain‚ specifically the left inferior parietal lobe. Lesions in the brain do not discriminate and can occur equally to genders‚ at any age. Natural brain lesions occur as a result of stroke‚ tumors‚ head injury‚ or hemorrhaging. Brain damage can be acquired in a number of ways‚ including neurosurgery
