Q

Non spiking vs spiking

A

spiking - APs binary, rate coded, temporal coded, digital
non spiking - analog/ continuous short rang slower - crab claw
nervous system is hybrid of both
amplitude of analog correlated with spike rate

17
Q

rate coded vs temporal coded

A

cell takes thinks how many spikes per bin

vs gaps also matter

18
Q

neurons as integration centers

A

integration of inputs with graded/weighted potentials by distnace from axon hillock

19
Q

types of networks

A

convergent
divergent
recursive
hidden layers

20
Q

edge detection

A

side ones less inhibited bla bla

21
Q

hopfield network

A

plasticity weights

22
Q

mauthner cells

A

contrallater control
fish and tad poles
reciperocal inhibition
visual sense mostly sometimes auditory

23
Q

DCMD

A

looming alert
like mauthner cell
biases movement but mauthner forces movement

24
Q

raster

A

trials over time

gets binned into histograms

25
interval spike interval
measure of time between spikes
26
autocorrelation histograms
detects rhythms
27
spike triggered average
average of trials shows where activity happens after even a single spike
28
NMJ steps
``` AP at synapse Ca influx vessicles with ACh leave ACh x2 bind to receptors letting in some Na depolarization opens more Na channels through T tubules into sarcpolasmic reticulum release callcium binds to troponin to remove tropomyosin contraction ```
