Q

What is the job of the executive control

A

It is the organizer
It will allocate resources to other subunits
It will monitor, manipulate and update memories

Q

Suggestibility

A

Persuading you to choose an answer or modify your memory

20
Q

Bias

A

Altering memories based on ones own beliefs

21
Q

Persistance

A

Remembering something when you are trying not to remember it

22
Q

What’s habitation

A

Learning to ignore a stimulus after repeated exposure

23
Q

What will cause short term habitation

A

Decrease in NT release

24
Q

What will cause long term habitation

A

Decrease in the number of synapses in the cell

25
Sensitization in memory response
Repeated stimuli can cause intense reflexes even with non-harmful stimuli
26
Sensitization in memory response
Repeated stimuli can cause intense reflexes even with non-harmful stimuli
27
What NT will serotonin increase and how
Will stimulate production of glutamate by releasing cAMP
28
What is consolidation
Conversion of short term memory into long term memory
29
What changes in the cell with short term memory
More NT are released and there are alterations to the Ca influx and K channels
30
What changes in the cell with long term memory
More synaptic connections More PKA CREB changes genes New proteins
31
What did the mutant fly experiment show
The importance of the cAMP pathway | They showed a decrees in implicit memory
32
What is Hebban plasticity
Explicit learning will occur when the synapse fires regularly. "If they Fire together, they are Wired together"
33
What is long term potentiation how long will it last
Long lasting increase in EPSP amplitude | From days to weeks
34
Where will long term potentiation occur
Hippocampus
35
What receptors are involved in Long lasting potentiation
AMPA | NDMA
36
What impact will the LTP have on the cell
Activates PKC Activates AMPA Activates NO (Retrograde)
37
What is normal depolarization in LTP
Normal functioning EPSP but will have no LTP
38
What is cooperatively depolarization with LTP
Small EPSP from multimode neurons. This may create LTP
39
What is Associativity with ATP
Simulates large and small depolarization and will have LTP in THESE NEURONS ONLY
40
Specificity in LTP
Stimulated neuron will have LTP Unstimulated neuron will not undergo LTP Ensures selective memory
41
What causes early LTP
Release of NT
42
What causes Late LTP
Synaptic connections in ore and post synapse
43
Where does spatial memory take place in the brain
The hippocampus
44
What is long term depression
A decrease in synaptic strength following a prolonged stimulus
45
What will remove AMPA receptors
Calcineruim caused by low levels of calcium | Will reduce action potentials
46
What will happen to the synapse connections as we gain new memories
Synapse connections are lost in order to develop new ones
47
What structure will change for memory be enhanced or repaired
Hippocampus will need to change
