1
What is neural integration
pre synaptic contact with many post synaptic’s that combine to affect firing of AP
2
What is a ligand
chemical that interacts with a receptor
3
What is the binding site
place on receptor where ligand interacts
4
What is affinity
how well ligand binds to receptor
5
What is an ionotropic receptor
‘directly coupled’ to ion channel
6
What is a metabotropic receptor
ligand binds to receptor, changes shape, activates G protein, can alter ionotropic or protein synthesis
7
What is negative feedback
release of NT can stop its own release
8
What can impact synaptic plasticity
retrograde signalling
9
What is glutamate
amino acid derivative
10
What is GABA
amino acid derivative
11
What is glycine
amino acid derivative
12
What are monoamines
bind to metabotropic
13
What is fMRI
measures activity via oxygen showing brightness in active areas
14
What is EEG
electrical signal on surface of scalp record change in polarity
15
What is MEG
combines benefits if other methods, needs cold sensors and stillness
16
What is intracranial electrophysiology
implants electrodes & records individual APs
17
Which brain can method has the best spatial resolution
single unit recording
18
Which brain scan method has the best temporal resolution
single unit recording
19
Which are synaptic NTs
glutamate, GABA, monoamines
20
Which are synaptic receptors
ionotropic, metabotropic, selective binding
21
What is synaptic plasticity
response to same input changes to encode in the brain
22
What is LTP
response increase
23
What is NMDAs role in LTP
induction
24
What is AMPAs role in LTP
expression
25
What are the properties of LTP
cooperativity, associativity, input specification
26
What is associative LTP
multiple inputs to a single output
27
What is LTD
decrease in response to same output
