Q

What is the amygdala involved in?

A

Emotionally arousing experiences

1
Q

Memory involves?

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

Lesions in amygdala result in?

A

Loss of conditioned fear and new fear learning

Reduced memory of emotional events

3
Q

Papez+amygdala=

A

Limbric system!!

4
Q

Paper consists of?

A

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

5
Q

Lesion in paper?

A

Impairment in declarative memories

Damage to arbitrary info

6
Q

Frontal lobes consist of?

A
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
Q

Confabulation?

A

Statements involving bizarre distortions of memory

8
Q

What does the diencephalon ( interbrain) consist of?

A

Thalamus and hypothalamus

9

‘Active retrieval’ of appropriate info

10
Q

Intracelluar/ midline?

A

Semantic memory (facts), memory retrieval

11
Q

Action potenicial

A

Find answer in book

12
Q

Synaptic plasticity?

A

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

13
Q

Long- term potentiation?

A

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

14
Q

Hebb’s rule?

A

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

15
Q

Other mechanisms of synaptic plasticity?

A
  • long term depression
  • habituation
  • sensitisation
