DynamicSpikingSynapse

The time varying state x(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

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.
