1

Implicit learning

unconscious long term memory that is inflexible as it is connected to the conditions where the info was learnt

2

Non-associative IM

learning about 1 type of stimulus where timing isn't important as the stimulus doesn't predict anything

3

Associative IM

learning relationships between 2 stimuli or stimuli-response

4

Habitulisation

active process of desensitisation

5

Sensitisation

enhancing a repose to a stimuli e.g. cocktail party phenomenon

6

Classical conditioning

learning the importance of a predictor stimuli

7

Operant conditioning

random activity becomes paired w/ +ve or -ve reinforcement

8

Long term potentiation

mechanism by which long-lasting, activity dependent changes in synaptic strength are generated by high frequency stimulation of the pre-synaptic neurone

9

Early LTP

involved increase in synapse sensitivity w/o gene transcription or mRNA translation

10

Late LTP

involves new gene transcription and mRNA translation = increase in no. of AMPA receptor and increase of size of synaptic connection
(involved in memory consolidation)

11

NMDA

normally blocked by Mg^(2+) ions

12

AMPA

normally allow Na+/K+ to enter cell when activated by glutamate (neurotransmitter)

13

NO

retrograde signalling molecule produced by CREB signalling + acts upon pre-synaptic bouton

14

(D,L)-AP5

NMDA-R antagonist that stops NMDA from functioning

15

Ca(v)1.2

voltage gated Ca2+ channel that plays a key role in LTP

16

Orientation

male fly recognises female (via vision + olfaction), then orientates so his head is behind her + taps on abdominal (taste)

17

Wing extension

wing closest to female head extends + vibrates (audition + olfaction signals for female) = mating song

18

Mean courtship index

total courtship time (s)/observation time (s)

19

Name the part involved in fly auditory processing.

Johnston's organ

20

Sexually dimorphic receptor

have difference responses in males and females e.g. cVA receptor

21

Name chemicals that a female fly secretes.

~ 7,11-HD
~ 7,11_ND

22

Name chemicals that a male fly secretes.

~ cVA
~7-T
~ 7-P
