Exam 3: Biological Foundations of Behaviour

When the resting potential is made more negative (e.g., moved from -70 to -73 millivolts), the neuron is said to be depolarized.

Agonists are drugs that can influence the activity of a neurotransmitter by doing one of the following EXCEPT:

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

The two divisions of the autonomic nervous system are:

Rohypnol and GHB are so-called 'date rape' drugs that work by enhancing the activity of which neurotransmitter?

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

The fact that young children typically have about 50 percent more synapses than adults do may best explain why:

Both the cerebellum and the basal ganglia are involved in the control of movement. However, they have very different roles. The basal ganglia is responsible for ________ Movement whereas the cerebellum is involved in movement.

Rafiel was at a party and drank a lot of alcohol. He had trouble walking in a straight line. Most likely, this is because the alcohol affected his

You are trying to get a good scan of a patient's brain in order to see where the area of greatest activity is. Which of the following would be the best scan to use?

You are looking at the electrical activity at a receptor site on the postsynaptic membrane. The measured potential is -80 millivolts (below the resting potential). How is this possible?

Neurotransmitters can have an excitatory effect or an inhibitory effect at the postsynaptic membrane. The difference between these two effects is that

The relatively greater localization of a brain function in one hemisphere or the other is called _.

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

While recording from a neuron, Dr. Chin noted that the neuron fired more rapidly as stimulus intensity was increased. But suddenly, the neuron would not fire any faster no matter how much the intensity was increased. What happened?

The resting potential of a typical neuron is:

Drugs such as cocaine, amphetamines, nicotine, and alcohol all stimulate the release of dopamine in the of the limbic system.

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

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

The resting potential of the typical neuron is determined by:
