Memory involves?

1. Papez circuit
2.frontal lobes
3. Dicecephalon
( think pretty freakin diddly)

1

What is the amygdala involved in?

Emotionally arousing experiences

2

Lesions in amygdala result in?

Loss of conditioned fear and new fear learning
Reduced memory of emotional events

3

Papez+amygdala=

Limbric system!!

4

Paper consists of?

Mammillary bodies, fornix, anterior thalamus nuclei (atn), cingulate gyrus and hippocampus. Think Mary Farts At Chloe's House

5

Lesion in paper?

Impairment in declarative memories
Damage to arbitrary info

6

Frontal lobes consist of?

Motor= motor and premotor cortices
Cognitive= prefrontal

If damaged impairment in appropriate encoding and retrieving, leading to impaired remembering of contextual details
However view can help

7

Confabulation?

Statements involving bizarre distortions of memory

8

What does the diencephalon ( interbrain) consist of?

Thalamus and hypothalamus

9

Dorsal medial?

'Active retrieval' of appropriate info

10

Intracelluar/ midline?

Semantic memory (facts), memory retrieval

11

Action potenicial

Find answer in book

12

Synaptic plasticity?

Biochemistry of synapses change to alter the effect on post- synaptic neuron

13

Long- term potentiation?

A long term increase in the excitability of a neuron to a particular synaptic input caused by repeated high frequency activity of input

14

Hebb's rule?

A excited b so much that something grows: changes and A's firing efficiency of B increases

15

Other mechanisms of synaptic plasticity?

- long term depression
- habituation
- sensitisation
