DynamicSpikingCbSynapse

The conductance g(t) of the synapse is increased by $W\cdot r \cdot u$ when a presynaptic spike hits the synapse and decays exponentially (time constant $\tau$ ) otherwise. u and r model the current state of facilitation and depression.

Read/writable Fields

E :
Equilibrium potential given by the Nernst equation.
U :
The use parameter of the dynamic synapse
D (sec) :
The time constant of the depression of the dynamic synapse
F (sec) :
The time constant of the facilitation of the dynamic synapse
u0 :
Value of the time varying facilitation state variable u for the first spike
r0 :
Value of the time varying depression state variable r for the first spike
tau (sec) :
The synaptic time constant $\tau$
W :
The weight (scaling factor, strenght, maximal amplitude) of the synapse
delay (sec) :
The synaptic transmission delay

Readonly Fields

u :
The time varying state variable u for facilitation
r :
The time varying state variable u for depression
psr :
The psr (postsynaptic response) is the result of whatever computation is going on in a synapse.
