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.
