Synaptic Plasticity

Question 1

types of memory

Answer 1

implicit and explicit

Question 2

is non-associative memory implicit or explicit?

Answer 2

implicit

Question 3

types of non-associative learning

Answer 3

habituation and sensitization

Question 4

habituation

Answer 4

form of learning where an organism stops or decrease response to repeated stimuli

Question 5

what is the difference between habituation, adaptation, and fatigue?

Answer 5

adaptation is when the organism no longer can detect the stimulus, while fatigue is when the organism can no longer respond to the stmulus

Question 6

what brain imaging techniques are used to observe habituation in the brain?

Answer 6

PET and fMRI

Question 7

is habituation a reversible condition?

Answer 7

yes

Question 8

mechanism of short-term habituation

Answer 8

repeated stimulus exposure&raquo_space; ESP by interneurons and motor neurons become smaller&raquo_space; motor neurons fire less&raquo_space; decreased reflex response

Question 9

mechanism of long-term habituation

Answer 9

4 spaced sessions of 10 stimuli&raquo_space; reduced synaptic release

Question 10

molecular mechanism of short-term habituation

Answer 10

decreased size of the total pool of synaptic vesicles

Question 11

molecular mechanism of long-term habituation

Answer 11

fewer docked vesicles, loss of synaptic connection

Question 12

sensitization

Answer 12

learning where an organism shows an increase in elicited behavior from repeated stimulus exposure

Question 13

mechanism of short-term sensitization

Answer 13

single harmful stimulus&raquo_space; increased in synaptic strength

Question 14

mechanism of long-term sensitization

Answer 14

5 spaced sessions of a single stimulus&raquo_space; sustained increase in synaptic strength (increased number of synapses)
