Exam 3: Biological Foundations of Behaviour

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 relatively greater localization of a brain function in one hemisphere or the other is called ________________.

Neurotransmitters that hyperpolarize a neuron are specifically called:

The fact that young children typically have about 50 percent more synapses than adults do may best explain why:

The area of the brain that produces orexins,a substance found to stimulate eating,is the:

The resting potential of a typical neuron is:

During brain surgery,a physician places a small electrode on various portions of the patient's exposed cerebral cortex.Though the patient is anaesthetized,he is still conscious and the physician asks him to report what he experiences when different parts of the brain are electrically activated.This physician is using which method of studying the relation between the brain and behaviour?

For most people,verbal,speech,and logical abilities are localized in the ______ hemisphere.

Severe damage to the ______________ results in severe motor disturbances characterized by jerky uncoordinated movements.

In the wilds of northern Canada,Joe is elk hunting with some college friends.After the hunters separate in search of a lone elk,Joe finds himself staring straight into the eyes of a grizzly bear.Joe's heart rate increases,and as he runs through the woods praying the bear is not following him,he is aware that he has never run faster.The nervous system responsible for Joe's speedy flight is the ______________.

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 band of myelinated nerve fibres that connects the right and left brain hemispheres is called the:

Though it was discussed in the context of the nervous system,the hypothalamus also plays an important role in the endocrine system because of its connection with the:

When Kimura,of the University of Western Ontario,presented stimuli-like letters,words,faces,and music to research participants such that the stimuli arrived first in either the left or right hemisphere,she found that:

Research has demonstrated that rat pups raised in stimulating environments had larger neurons with more dendritic branches.Similarly,musicians who do complex string work with their left hands tend to have larger corresponding somatosensory areas.These are both examples of:

The memory of a woman is substantially impaired after she injures her head falling off of a ladder.In particular,she is unable to remember recent events that have happened to her.Damage to which of the following brain areas is most likely responsible for these difficulties?

Which of the following examples is most relevant regarding communication between the nervous system and the immune system?

Branch-like fibres that collect messages from adjacent neurons and pass them along to the cell body of the receiving neuron are called _______________.

The presence of many branches on the axons makes it possible for a single neuron to connect to the dendrites of as many as 50,000 other neurons.The branches on the axons are called ___________:

Agnosia is the inability to identify familiar objects.The area of the brain that is responsible for this is the _____________ .
