A neuron's action potential is also known as a(n) ___________.

Alex a was at a party and by the time she got home, she could not walk in a straight line. You know that she took a drug that suppressed the activity in her cerebellum. What was the drug?

What is the term for a neurotransmitter that merely indirectly modifies the effect of another neurotransmitter (e.g. increases the effect that glutamate has when it binds), as opposed to more directly producing an excitatory or inhibitory effect as a direct consequence of binding to a receptor itself?

It is relatively easy to see how there can be trillions of interconnections in the brain, given the diverse structures of the ______________.

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

The somatic sensory cortex is located in the _________________ lobe.

The structure that plays a major role in emotional and motivational behaviours, including sexual behaviour, temperature regulation, sleeping, eating, drinking, and fighting or fleeing is the ______________.

If you wanted to prolong the effects of a neurotransmitter it would be best to use a drug that

A patient has received a diagnosis of Parkinson's disease. Which area of the brain is affected?

Wernicke's area is primarily concerned with speech production, whereas Broca's area is related to speech comprehension.

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

A criminologist is interested in the neurological study of people who commit violent murders. Where would you suggest that she focus her attention?

What is the possible relation between the hypothalamus and the limbic system regarding emotion and motivation? What roles do the hippocampus and amygdala play in psychological functions?

As you are driving, another car pulls out unexpectedly from a side road. You find that your heart rate increases and you are breathing faster. This is because of activation in the

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

Your friend is trying to teach you how to play guitar. You've taken a few lessons with them already and they are now trying to show you how to play a new chord. You watch them play the chord a few times before picking up your own guitar and trying it yourself. You strum the strings with your right hand, meaning you use the fingers on your left hand to manipulate the strings on the guitar neck. What phenomenon can account for the physical changes in the brain that could result from extensive practice of guitar playing?

If the patients with their corpus callosum severed were shown a picture of a hairbrush in their right visual field, then the patients would _____________.

Neurons are the basic building blocks of the nervous system. They operate by generating ____________ and releasing ___________.

A new drug has the effect of opening sodium channels at the postsynaptic membrane. The result at the postsynaptic membrane is likely to be

Neurotransmitters travel across the synapse and bind to the ___________ of neighboring neurons in a lock and key fashion.
