1
Q

Implicit learning

A

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

2
Q

Non-associative IM

A

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

3
Q

Associative IM

A

learning relationships between 2 stimuli or stimuli-response

4
Q

Habitulisation

A

active process of desensitisation

5
Q

Sensitisation

A

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

6
Q

Classical conditioning

A

learning the importance of a predictor stimuli

7
Q

Operant conditioning

A

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

8
Q

Long term potentiation

A

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

9
Q

Early LTP

A

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

10
Q

Late LTP

A

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
Q

NMDA

A

normally blocked by Mg^(2+) ions

12
Q

AMPA

A

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

13
Q

NO

A

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

14
Q

(D,L)-AP5

A

NMDA-R antagonist that stops NMDA from functioning

15
Q

Ca(v)1.2

A

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

16
Q

Orientation

A

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

17
Q

Wing extension

A

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

18
Q

Mean courtship index

A

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

19
Q

Name the part involved in fly auditory processing.

A

Johnston’s organ

20
Q

Sexually dimorphic receptor

A

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

21
Q

Name chemicals that a female fly secretes.

A

~ 7,11-HD

~ 7,11_ND

22
Q

Name chemicals that a male fly secretes.

A

~ cVA
~7-T
~ 7-P
