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
\[\begin{split} P'(t) = ( 1 - P ) / \tau_P P(T+) = (1 - \delta_P) P(T-) \text{ for T : time of a spike } \\ P(t=0) = 1 \end{split}\]\[ w(t) = w_{max} * P(t) \]is the resulting synaptic weightParameters:
The following parameters can be set in the status dictionary:
tau_P
ms
Synaptic vesicle pool recovery time constant
delta_P
real
Fractional change in vesicle pool on incoming spikes (unitless)
P
real
Current size of the vesicle pool [unitless, 0 <= P <= 1]
