Exam 3: Biological Foundations of Behaviour

Before an action potential can begin, the neuron's membrane must

Small variable changes in the electrical potential of a neuron that occur in the dendrites and cell body are called ___________.

After a neuron has sent a nerve impulse, it has to rest for a few milliseconds. This has important implications for neuronal firing because it places an upper limit on firing rate. This is referred to as _____

Name the three main parts of the neuron and describe their functions.

Joel was in a car accident and banged his head. When the ambulance arrived at the hospital, he was unable to hear. Most likely, Joel hit an area on

One of the reasons it's important never to move someone who's been in a car accident unless absolutely necessary is that broken bones in the neck could damage the spinal cord or the ____________, which is the part of the brain responsible for breathing and heartbeat.

What is the effect of the myelin sheath on the conduction of neural impulses?

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

Kyle is a successful trial attorney, particularly adept at his ability to verbally out maneuver his opponents in the courtroom. Last month Kyle was diagnosed with a degenerative brain disorder. Kylenow wonders how long he will be able to continue working because he is having trouble understanding what his clients are telling him. He hears the words; he is just unable to make sense of their meaning. Which area of the brain would doctors say is most likely involved in his disease?

Two important structures in the limbic system are

The prefrontal cortex is responsible for the _____________.

Describe two methods by which neurotransmitter molecules are deactivated at the synapse.

Neurons have three main parts, they are the ___________.

One of the ways in which researchers have learned about lateralization is by studying what are referred to as 'split-brain' patients. These patients have had the connection between the right and left hemispheres of their brain cut. This connection is called the

The primary job of the amygdala is to

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 (which requires more control than what your strumming hand is doing). Assuming that you continue practicing your guitar playing, what change in your brain could be predicted?

Joel was in a car accident and banged his head. When the ambulance arrived at the hospital, he was unable to see. Most likely, Joel hit

The basal ganglia plays an important role in

Which of the following drugs is considered to be an agonist for the neurotransmitter acetylcholine?

How is language lateralized in the brain? Are there sex differences?
