Question 1

The population of cholinergic cells at the ventral surface of the striatum are ______________.

Answer 1

Broca’s diagonal band

Question 2

Which part of the amygdala is the input section?

Answer 2

Basolateral

Question 3

The output nucleus of the amygdala is the ______________.

Answer 3

Question 4

True or false: channelrhodopsin allows the entry of sodium channels.

Answer 4

True, but it also allows the exit of potassium channels.

Question 5

How do researchers make selective channelrhodopsin?

Answer 5

By transfecting it into viruses that bind to certain surface proteins; in doing so, they can make only cholinergic cells (for instance) selectively express channelrhodopsin.

Question 6

Answer 6

novelty reward

Question 7

The ____________ generates fear response.

Answer 7

Answer 9

dopaminergic mesolimbic

Question 10

Severing the frontal lobe’s connections to the rest of the brain leads to ________________.

Answer 10

impaired ability to estimate risks and rewards and to then calibrate behaviors to coordinate with those risks and rewards (including even the ability to have a “gut feeling” about likelihood of risks and rewards)
