Charge stored on a neuron per spike

Hello nengo_dl community,

I hope you are doing well.

I am working with MNIST tutorial on nengo_dl and I would like to know:
how can I find the amount of charge that is stored on a neuron when it receives one spike?

Thank you for your answer in advance.

Hi @Choozi,

I’m not entirely sure what you mean by “amount of charge stored on a neuron”. Do you mean the neuron membrane potential? If that’s the case, you should be able to get that by probing the neuron’s voltage. I haven’t actually tested it in a NengoDL model, but you should be able to use the output of the probe like other Nengo probes (see this example).
