SpikeRefractoryMixin¶

class SpikeRefractoryMixin(refrac: Tensor, absrefrac: str)[source]¶

Bases: RefractoryMixin

Mixin for neurons with refractory periods with spikes based off of them.

Parameters:

refrac (torch.Tensor) – initial refractory periods, in \(\text{ms}\).
absrefrac (str) – attribute containing the absolute refractory period, in \(\text{ms}\).

property spike: Tensor¶

Action potentials last generated.

\[\begin{split}f(t) = \begin{cases} 1, &t_\text{refrac}(t) = \text{ARP} \\ 0, &\text{otherwise} \end{cases}\end{split}\]

Where:

\(f_(t)\) are the postsynaptic spikes.
\(t_\text{refrac}(t)\) are the remaining refractory periods, in \(\text{ms}\).
\(\text{ARP}\) is the absolute refractory period, in \(\text{ms}\).

Returns:

if the corresponding neuron generated an action potential: during the prior step.

Return type:
