ht_synapse


Name:
ht_synapse - Synapse with depression after Hill & Tononi (2005).
Description:
 
This synapse implements the depression model described in [1, p 1678].
See docs/model_details/HillTononi.ipynb for details.

Synaptic dynamics are given by

P'(t) = ( 1 - P ) / tau_P
P(T+) = (1 - delta_P) P(T-) for T : time of a spike
P(t=0) = 1

w(t) = w_max * P(t) is the resulting synaptic weight

Parameters:
 
The following parameters can be set in the status dictionary:
tau_P double - synaptic vesicle pool recovery time constant [ms]
delta_P double - fractional change in vesicle pool on incoming spikes
[unitless]
P double - current size of the vesicle pool [unitless, 0 <= P <= 1]

Sends:
SpikeEvent
