Exam 3: Biological Foundations of Behaviour

Derek has been asked to hand-deliver a message to Adeline. Adeline lives across the river from Derek, and there is no bridge; therefore, Derek must take a boat across the channel. When he reaches the shore, he ties the boat to the dock so he can take the message to Adeline. If we compare Derek's actions to those that occur in neurons, we can say that the dock, where Derrek binds his boat, is like a

Moesha's little brother hides in her closet. When she opens the door, he leaps out and yells, "Boo!" She screams, jumps backward, and clutches her chest, because her heart is pounding. Moesha's ________________ nervous system is responsible for her reaction.

The chemical substances that neurons produce which carry messages across the synapse to the other neurons are called _______________.

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 worst scan to use?

Research on neural plasticity indicates that brain damage is more devastating

Martin has a history of violent criminal behaviour because of his inability to consider the consequences of his actions or control his impulses. As a neuropsychologist, which cortical area do you think is most likely to be dysfunctional in him?

When your body gets too warm, you begin to sweat, your skin flushes, and you're likely to seek out cooler surroundings. When your body gets too cool, you get goosebumps, you shiver, and you're likely to seek out warmer surroundings. These behaviours are evidence that your body likes to maintain an internal balance called _________________ to keep you safe and healthy.

The structure of the human brain can be said to mirror evolutionary development because the _____________.

New brain cells have developed in Rodney's brain. This process is known as ___________.

The branchlike fibres that collect messages from the adjacent neurons and pass them along to the cell body of the receiving neuron are called ________________.

Neurotransmitters that increase the negative potential of a neuron are specifically called ___________.

Under very controlled laboratory conditions, split-brain patients show some very interesting phenomenon. In particular, if these patients are made to focus on a fixation point and they are flashed a picture of a hammer in the left visual field, they

The cortex that is responsible for the control of approximately 600 muscles involved in voluntary bodily movements is called the __________ cortex.

What is hemispheric lateralization, and what do we know about the functions that are concentrated in the left and right hemispheres?

Which of the following represents the normal order of activation in neuronal transmission?

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

Multiple sclerosis occurs when a person's own immune system specifically attacks

Describe the roles of (a) acetylcholine, (b) dopamine, (c) serotonin, and (d) endorphins in psychological functions.

A friend of yours was at a party and took some drugs. He is euphoric but doesn't know what he took. Another friend told you that the drug works solely by blocking reuptake. What kind of drug did your friend take?

What function does the midbrain play? What structure is buried within the midbrain? What is its function?
