Characters of Synaptic Transmission
Fatigue
Benefit
: stablilize nervous system .eg.Epiletic seizures
Decreased
discharge of impulses from presynase
Cause
:
inactivation of postsynaptic receptor
deplletion of syanptic vesicles
Forward Direction
Impulses conducted only from presynaptic to postsynaptic
Cause
: Neurotransmitter formed and released from presynaptic
Synaptic Delay
Time
taken by an impulse to conduct through synapse (0.5ms)
Causes
its
union
with the receptor
opining
of ionic gates
Release
of chemical transmitter
efflux
of ions and
bulding
postsynaptic potential
Synaptic Plasticity
Importance
: represnt form of learning and memory
Forms
Long term
Long term depression
LTP
Short term
Sensitization
PTP
Habituation
Def
: ablilty to change function to achive a demand
