Exam 3: Biological Foundations of Behaviour

Caffeine is an antagonist and therefore it is an example of a drug that:

The primary job of the ascending reticular formation is to:

Which of the following statements about the motor cortex is true?

Research,like that conducted by Roy Wise of Concordia University in Montreal,has provided evidence that the area in the brain important for the value of reward and motivation is:

The medulla plays an important role in the coordination of muscular movement and also in and memory.

The action of an ____________ neurotransmitter from one presynaptic neuron may prevent the post-synaptic neuron from reaching the action potential threshold.

The ______________ cortex is located at the very back of the frontal lobe and controls the more than 600 muscles involved in voluntary body movements.

When an electrical charge of a neuron reaches the action potential threshold,its voltage momentarily goes from -70 millivolts to +40 millivolts in a process that is called __________.

The job of the sensory neurons is to transmit neural impulses from the sense organs to the brain.

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

The area of the brain that is responsible for self-awareness,planning,and initiative is called the ___________ lobe.

The unique findings of split-brain research are primarily due to the fact that:

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

The two ways that neurotransmitters can be deactivated are:

The __________ method of studying brain behaviour is capable of examining both brain structures and brain activity.

The gaps between segments of myelin sheath that occur at regular intervals are called:

Ursula is sound asleep one night when she is suddenly awakened by a loud noise coming from her backyard.She gets out of bed and moves to the window in order to see what made the noise.Ursula is relying on her ______ nervous system.

Alcohol effect on the brain is as a(n):

The reticular formation is considered to be the "brain's gatekeeper" because:

The three main parts of the neuron are the axon,cell body,and dendrites.
