Olfaction
Memory

2

Which tract is next to the fornix?

Stria terminalis

3

What is declarative learning?

Learning of facts

4

The hippocampus is necessary for ___________ learning.

declarative; the cerebellum is necessary for procedural learning

5

Working memory (i.e., short-term tasks) is mediated by _____________.

the frontal lobes

6

Long-term potentiation occurs in the _______________ via ______________.

hippocampal cortex; simultaneous, reinforcing stimuli

7

The hippocampus uses which neurotransmitter?

Glutamate

8

Describe the location of the ventral tegmental area.

Just medial to the substantia nigra

9

Mood is to affect what climate is to ____________.

weather

10

In the processing of negative memory, which parts of the amygdala receive input from the cerebral cortex?

The basolateral and lateral nuclei; these then project to the central nucleus

11

The _____________ is the main output sector of the amygdala, mediating control of expression.

central nucleus (abbreviated CEA for some reason)

12

The basolateral and lateral nuclei project to the ____________ for positive conditioning (rewards) and ____________ for negative conditioning (punishments).

ventral tegmental area (brainstem); central nuclei

13

Research shows that fear associations do not disappear by ____________, but rather _____________.

extinction; an inhibitory memory rises to supplant them (mediated by the medial prefrontal cortex)

14

The stria terminalis connects _________________.

the amygdala to the hypothalamus
