plasticity and synaptic intergration Flashcards
topology
what happens after shape is changed
localisations within somatosensory cortex
although shape is altered neighbours stay neighbours
how many layers in the cortex
6 layes mainly neutrites and synapses
problems with motor control
longest axon cells dies first
axon transport makes them valnurable
Lambda- length constant
decay over a distance around mm in giant axon
if you move enough ions to change the voltage
what puts a limit to how fast the brain works
time constant - tau
saltary AP transmission happens in
mylenated axon
voltage clamp
what is it
what does it do
space and current controller, controlling voltage
determination of ionic basis of AP
patch clamp of v. gated Na channels
what is it
what does it do
records individual channels
holds the voltage where you want it
allows to see changes in protein
opening closing
modality what is it
it is coded by which axon is activated
which axon determines which muscle
intensity what is it
coded by number of ap
ap frequency is proportional to the log of stimulus intensity
transduction
change from AP to release of NT
signal transduction is
changes in ionic gradient, AP, which have to be transduced in order to produce physiological action
excitation inhibition is essential for
neurocomputation
glutamate receptors what are they blocked by
Mg
GABA receptors have what kind of opening
smooth opening then fluctuates
