Flashcards in Learning and Memory Deck (19):
1

By when do we have most of our brain cells?

By birth

2

What happens in brain development between the ages of 0 and 3?

Synaptogenesis

3

What happens in brain development after the age of 3?

Synaptic pruning

4

What was patient HM unable to do?

Convert short-term memories to long-term memories

5

In what part of the brain did HM have a lesion?

Bilateral medial temporal lobe

6

Are memories encoded in just one area of the brain?

No

7

What part of the brain encodes declarative memories?

Hippocampus
Medial temporal lobe
Diencephalon

8

What part of the brain encodes skills and habits?

Striatum
Motor cortex
Cerebellum

9

What part of the brain encodes emotional responses?

Amygdala

10

What part of the brain encodes skeletal musculature from basic associative learning?

Cerebellum

11

What encodes non-associative learning?

Reflex pathways

12

Where are memories stored?

Hippocampus

13

What improves learning and memory in mice with brain damage?

Enriched environments > increased neuronal plasticity

14

How does neuronal plasticity change with age?

Decreases

15

How is short-term memory stored?

Insertion of AMPA receptors
Phosphorylation of receptors
Enhanced pre-synaptic release via retrograde signalling

16

How is long-term memory stored?

Protein synthesis
Structural changes

17

What does exercising the brain do?

Release of growth factors
Generation of new neurons
Improvements in mood and memory

18

What does exercise do to the brain?

Increases blood flow
Elevates mood

19

How does early physical exercise improve stroke outcome?

Very early rehab (
