Exam 3: Biological Foundations of Behaviour

Alcohol affects the brain by stimulating the activity of GABA,thereby depressing neural activity.

The changes in the electrical potential of a neuron that do not reach -50 millivolts are called:

The ___________________ is a fatty,whitish layer of insulation found on many axons that transmit information throughout the brain and spinal cord.

The association areas in the cortex are where sensory information is first processed.

The brain is capable of _________ plasticity in young children compared to adults.

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:

________________ occurs when transmitter molecules are reabsorbed into the presynaptic axon terminal.

The effects of a psychoactive drug are determined not by which chemical transmitter the drug targets,but by the drug's actions at the synapse.

Scientists have suggested that the entire period of human evolution could be labelled "the age of the ___________ lobe."

Branchlike fibres that collect messages from adjacent neurons and pass them along to the cell body of the receiving neuron are called ____________.

Shamay-Tsoory and colleagues found that psychopaths have a deficit in their __________ compared to healthy controls.

Which of the following is an inhibitory neurotransmitter found throughout the brain,especially important in anxiety and motor control?

That action potentials occur at a uniform and maximum intensity or they do not occur at all is known as:

The electroencephalogram,or EEG,was discussed as an example of the _____________ method of studying brain-behaviour relations.

Ron,a middle-aged bank executive,is in excellent health.Ron jogs five miles four times a week,keeps his weight at a healthy point,and eats a well-balanced diet.He is particularly worried about the effects of aging as both his parents developed Alzheimer's disease in their later years.Recently Ron has been receiving Botox injections to reduce the wrinkles on his forehead.Little does he know that the Botox injections he receives and the aging disease he so dreads have this same neurotransmitter in common:

Research on gender differences in the hemispheric localization of language has revealed that:

Control of approximately 600 muscles involved in bodily movements is determined by the ____________ cortex.

Research by Shamay-Tsoory and colleagues on criminals with antisocial personality disorder may have deficits in what area?

One of the primary functions of the thalamus is to:

Research on gender differences in the lateralization of language has revealed that the brains of men and women are essentially the same with regard to this function.
