Example for homeostatic plasticity with firing rate

[schmitts]

Hi!

I'm looking for an example for homeostatic plasticity to stabilize firing rates. Is there a notion for firing rates available that can be used to formulate a weight update rule?

Thanks,

Sebastian

Hi. Just as a general remark: our forum on https://brian.discourse.group would be a better place to ask this kind of question.

In spiking networks, there is no direct firing rate variable that is available. What you'd typically do is to use a variable that increases with each spike (via the reset statement) and decays over time. Another option is to low-pass filter the membrane potential and to use this as a proxy for the firing rate (see e.g. the Clopath et al. (2010) example).

Thanks. Will continue on discourse.
