ht_synapse – Synapse with depression after Hill & Tononi (2005)¶
Description¶
This synapse implements the depression model described in [1, p 1678].
Synaptic dynamics are given by
\(w(t) = w_{max} \cdot P(t)\) is the resulting synaptic weight
For implementation details see: HillTononi_model
Warning
This synaptic plasticity rule does not take precise spike timing into account. When calculating the weight update, the precise spike time part of the timestamp is ignored.
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] |
