Q

What is in the neural circuit for implicit memory? think picture of brain

A

Premotor Cortex, basal ganglia, thalamus, and substainia nigra

17
Q

What is consolidation?

A

a process lasting for hours to fix information into long term memory

18
Q

What is evidence for consolidation?

A

Forgetting curve

19
Q

What are the theories for forgetting?

A

Interference and decay

20
Q

What is decay?

A

Memory trace fading

21
Q

What is interference?

A

memory trace interrupted by other materials

22
Q

What happens to memory during decay?

A

how much memory is retained depends on how much time has passed

23
Q

What happens to memory during interference?

A

Memory is more forgotten the more interpolated events occur.

24
Q

What is the relationship between consolidation and sleep?

A

more sleep you get is the more information that is fixed into long term memory

25
What is dementia?
Impairment in memory caused by progressive cell death
26
How is it characterised?
memory impairment, social impairment, impairment in executive functions. agnosia, apraxia, aphasia
27
What is degenerative dementia presumed to have?
Genetic cause
28
What is cortical dementia?
Alzheimer's
29
What is subcortical dementia?
Parkinsons
30
What is Alzheimer's disease?
Progressive disease with memory impairments
31
Alzheimers: What are the memory impairments?
semantic memory learning and learning new information
32
What are the language defects?
list generation, word finding, less complex sentences
33
What are the visual-spatial defects?
visual recognition and spatial awareness
34
What are the executive function impairments?
Planning, predicting
35
Where does cortical degeneration happen?
Entorhinal cortex, which explains why memory is the first to go
