Exam 3: Biological Foundations of Behaviour

Split-brain research was made possible originally by surgical techniques done to limit the potential brain damage caused by epileptic seizures.This was accomplished by cutting the _________________

Mental imagery,the ability to understand spatial relationships,and musical and artistic abilities tend to be located:

The system that consists of numerous glands distributed throughout the body is called the:

The job of the thalamus is to organize sensory input and route it to the appropriate brain areas.

Acetylcholine (Ach)is known to be involved in:

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.

During the chemical communication process,neurotransmitters cross the synapse and attach themselves to receptor sites on the postsynaptic neurons.This stage is called _____________:

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.

An oversupply of dopamine,a neurotransmitter that can be excitatory or inhibitory,has been implicated in schizophrenia,and an undersupply of dopamine has been implicated in depression.

The resting potential of the typical neuron is determined by:

In both the sensory and motor cortexes,the amount of cortex devoted to each area depends upon the ___________ of the movements that are carried out by a particular body part.

Brain research has indicated that mathematical,verbal,and logical abilities tend to be located in the left hemisphere for most people.This is an example of what is technically called:

Antigens are most relevant to the functioning of the:

After a very loud noise in her backyard woke her from a sound sleep,Ursula is lying in bed paralyzed by fear.Her heart is pounding,her face is flushed,and there is a sinking feeling in the pit of her stomach.The nervous system that is responsible for Ursula's body reactions to the noise is called ________________:

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 _______.

Computerized axial tomography (CAT)scans,positron emission tomography (PET)scans,and magnetic resonance imaging (MRI)are all examples of which method of measuring brain-behaviour relations?

Alexis is riding her bicycle to school one day and slides on some loose gravel at the bottom of a hill.Her bike flies out from under her and she looses consciousness.At the hospital Alexis does not seem oriented to the situation and cannot remember even riding her bike let alone falling.The doctors wish to take pictures of the structure of her brain to determine whether or not there are injuries.To do this,they use a _______________:

The primary job of the ascending reticular formation is to:

Lucy and her older brother Louis have developed quite a fierce sibling rivalry.On vacation in Mexico with their father,Louis and Lucy were being relatively well-behaved until one afternoon when Lucy accidentally stepped on her brother's foot and he automatically punched her.Louis apologized profusely saying that he just reacted and didn't even have time to think about what he did before he did it.Louis might try to claim that his brain was unaware of what he was doing at the time he punched Lucy because this type of response is considered a:

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.
