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

@f[
P'(t) = ( 1 - P ) / \tau_P
P(T+) = (1 - \delta_P) P(T-) \text{ for T : time of a spike } \\
P(t=0) = 1
@f]
@f[
w(t) = w_{max} * P(t) @f] is the resulting synaptic weight
Parameters:
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]
