Learning And Memory

Question 1

Long-term potentiation

Answer 1

Long-term increase in the strength of the connection between two neurons

Question 2

Long term depression (LDP)

Answer 2

Long-term decrease in the strength of the connection between two neurons

Question 3

2 factors that determine if the synapse gets stronger or weaker

Answer 3

1- how often the synapse was activated
2- how often that cell actually spiked as a response

Question 4

Nmda receptor is gated by 2 things

Answer 4

1- glutamate has to bind to it for it to open
2- in order for the current to flow in, the membrane potential has to be a certain amount

Question 5

Perceptual learning

The more you perceive things the more you are able to recognize them as distinct entities

Question 6

Motor learning

Answer 6

The more we do an action, the better we get at it

Question 7

Relational learning

Answer 7

Stimulus-reponse learning

Answer 8

Learning to perform a particular behavior when a particular stimulus is present. Includes classic and instrumentam conditioning

How u move considering your environment

Question 10

Is hippocampus needed to remember old events?

Answer 10

No! frontal lobe can reactivate on its own

Question 11

Injecting anastbesic in the hippocampus (like if no hippocampus)

Answer 11

Rodent after 30 days, can remember how to do the maze (after 30 days, dont need the hippocampus anymore, the cortex knows how to do it)
