Exam 2 Flashcards
Electircal synapses
faster,
bidirectional
connexin Cx36 in PFC Neurons
Cx43 in astrocytes
connexin
hexamer
can be closed
usually closed
some secondary messengers
nervous system cells with electrical synapses
in PFC
layers connected for lateral inhibition
knockouts of Cx36
reduces fine motor skills
Chem Type I
Asymmetrical
EPSP
form on dendrites
Chem Type II
Symetrical
IPSP
on Soma
chemical
slower
vessicals
diff between pre and post
Temporal summation
happen really fast to reach threshold
Spatial summation
happen nearby to reach threshold
IPSP vs EPSP
EPSP depolarization letting Na
IPSP hyperpolaration letting Cl in and Na out
EPSP Nts
glutamate, serotonin, ACh
IPSP
GABA and glycine
G protein coupled receptors GPCRs
slow synapse
monamine NTs
glutamate receptors
NMDA, AMPA
inclusive fitnes
Catholicism
move breed survive
Non spiking vs spiking
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
rate coded vs temporal coded
cell takes thinks how many spikes per bin
vs gaps also matter
neurons as integration centers
integration of inputs with graded/weighted potentials by distnace from axon hillock
types of networks
convergent
divergent
recursive
hidden layers
edge detection
side ones less inhibited bla bla
hopfield network
plasticity weights
mauthner cells
contrallater control
fish and tad poles
reciperocal inhibition
visual sense mostly sometimes auditory
DCMD
looming alert
like mauthner cell
biases movement but mauthner forces movement
raster
trials over time
gets binned into histograms
