Flashcards in The Limbic System Deck (14):
1

What is Sommer's sector?

Part of the hippocampus (CA1) region which is VERY sensitive to hypoxia

2

Contains a pyramidal layer made of pyramidal neurons

Hippocampus

3

Serves as the main integrator of the autonomic and endocrine systems

Hypothalamus

4

believed to participate in memory acquisition, subjective experience of emotions and, via the autonomic nervous system, the visceral manifestations of emotions

Hippocampus

5

This is a circuit linking the hippocampus with the cingulate cortex

Circuit of papez

6

What must be intact in order for new memories to be created?

The circuit of papez must be intact in at least one hemisphere in order for new memories to be acquired

7

Where does the hippocampus send its fibres?

To the mamillary body of the hypothalamus

8

What is required for learning an association between 2 stimuli (e.g. name and face)?

An intact hippocampus

9

Required for recalling the memory for a time after it is acquired?

Hippocampus

10

Anterograde amnesia

Inability to form new memories

11

Retrograde amnesia

Inability to recall memories before the onset of amnesia

12

Temporally graded retrograde amnesia

Patient can recall remote events more easily than recent ones

13

The pyramidal layer in the hippocampus is made of three layers, what are these layers and which one is most sensitive to hypoxia?

CA1, 2 and 3

CA1 is most sensitive to hypoxia

14

This structure has a role in evaluating the significance of environmental events and the association of environment events and reinforcement

Amygdala
