1
Q

perceptual learning

A
  • you recognize things youve seen before quicker
2
Q

S-R learning

A

= stimulus-response learning

- classical and operant=instrumental conditioning

3
Q

classical conditioning

A
  • natural stimulus linked to initially neutral one

- produces automatic response

4
Q

instrumental conditioning

A

= operant conditining

  • learning relatoin between stimulus and expexted behavious
  • reward and punishment
  • produces learned response
5
Q

motor learning

A
  • learning motor skill

- f.e. riding a bike

6
Q

Hebb rule

A
  • fire together wire together
7
Q

relational learning

A
  • semantic
  • episodic
  • spatial
  • always declaritive/explicit
8
Q

S-R learning neurological

A
  • hardwired natural response connection
  • fires together with weak one
  • LTP occurs
9
Q

Associative LTP

A
  • LTP for S-R learning
10
Q

requirements LTP

A
  • axon is active by secreting glutamate

- depolarisation of postsynaptic

11
Q

NMDA receptors

A
  • blocked by magnesium

- removed by depolarisation -> Ca2+ channels open

12
Q

Ca2+

A
  • 2nd messenger
  • activates enzyme CaM-KII
  • that creates new AMPA receptors
13
Q

pleasure center

A
  • connectin between nucleus accumbens + dopaminergic VTA
14
Q

patients HM and CW

A
  • anterograde amnesia

- absence of new declarative memory storage

15
Q

retrograde amnesia cause

A
  • hippocampus lesion
  • the more the worse
  • combined with medial temporal: 30 years back
16
Q

hippocampus in memory

A
  • only for putting new memories in other areas
17
Q

reconsolidation

A
  • memories are retrieved to be changes

- vulnerable in that state

18
Q

erasing memories

A
  • ECS to induce epileptic seizure
  • causes loss of short-term memory
  • > currently retrieved memories are los
