Exam 3: Biological Foundations of Behaviour

As a result of a head trauma,a man loses his ability to talk,but can still understand what people say to him.He has most likely suffered damage to which part of the brain?

The vision area of the brain is located in the temporal lobe.

A person who has just suffered a head trauma due to a car accident is given the "Trail Making Test" by a psychologist in order to assess the person's memory and planning abilities.This test is an example of which method of studying brain-behaviour relations?

Scientists used to think that neurons communicated with each other through direct physical contact.With the advent of the electron microscope,the synapse or gap between neurons is evident and it is apparent that rather than direct contact,the communication continues through ____.

The drug Prozac has a positive effect on depression by:

What are the three major types of neurons in the nervous system?

The unique findings of split-brain research are made possible when the ______________ of people with severe seizures is cut to minimize the potential brain damage caused by these seizures.

Adrian Raine and his colleagues argued that violent murders illustrate a failure in executive function,such as lack of judgment and impulse control.In support of this argument,using PET scans on a group of violent murderers who plead not guilty by reason of insanity,these researchers found reduced activity in the ________.

The electroencephalogram (EEG)is an example of which method of assessing the relation between the brain and behaviour?

The Chinese language uses complex pictorial images instead of words,and recent research suggests that there is less left hemisphere lateralization of language in Chinese people than in people who use languages based on alphabets.This is thought to be the case because:

Graded potentials are directly proportional to the amount of incoming stimulation,while action potentials are not.

After a neural impulse passes a point on the axon,the period during which the membrane cannot discharge another potential is called depolarization.

Sean is a split-brain patient who volunteers to demonstrate to Dr.Jones' psychology classes the effects of his condition.Dr.Jones controls whether objects are presented to either Sean's right or left visual field.When Dr.Jones presents an ordinary pencil to the right side of Sean's visual field,he is _________ due to the language-rich ________ hemisphere.

In a large communication network such as the National Telephone Company,the actual cables and transmissions could be analogous to the body's neurons,while the technicians and mechanics that support the equipment are analogous to the body's __________.

Abnormally high levels of dopamine have been observed in the brains of people with:

This area of the brain is located in the temporal lobe and is involved in speech comprehension:

While the hypothalamus is known to play a role in the formation of motivational and emotional urges,it is thought that the coordination of the behaviours needed to satisfy these urges is performed by the _______.

The prefrontal cortex is the location of the so-called ____________,which are mental abilities that involve such things as goal setting,strategic planning,and impulse control.

A man injures his head in a construction accident.After the incident,he shows a great deal of apathy towards people and things,is emotionally flat,and doesn't seem to care about anything.This person mostly likely suffered damage to his __________ cortex.

_______________ are significantly more numerous than the two other types of neurons and serve connective or associative functions in the nervous system.
