Hi,

This is a very basic question. I just started looking into Brian. I understand it is a **spiking neural network simulator**. Even the example for a “Rate model”, the threshold condition is set to Poisson, so that Poisson-distributed spikes are generated. But “threshold” is an optional parameter, so what happens if it is not set ? Does the neuron group then just have a voltage, and if another neuron group receives input from this one, it functions as a real “rate model” where there are no spikes - i.e. a dynamic field model, or neural field model etc … (sorry if I mangling the semantics here).

So, after posting, I asked GPT-4 and it says that if threshold is not set, then no spikes will be fired, and if this neuron group is used as input to another, then there will be no input from this neuron group to the other. Is this correct ? (If yes, perhaps GPT-4 can write Brian documentation ?).

Thanks !
