Can anyone help me find the location of the NetCon code? I'm trying to follow how the NetCon weight parameter is implemented in the ExpSyn equations. I'm assuming the weight added to g is from the NetCon, but is g at kept <=1 by another piece of code? Thanks in advance.

Part of the ExpSyn.mod file:
BREAKPOINT {
SOLVE state METHOD cnexp
i = g*(v - e)
}

DERIVATIVE state {
g' = -g/tau
}

NET_RECEIVE(weight (uS)) {
state_discontinuity(g, g + weight)
}

Why would you want to keep g<=1? g is the conductance of a synapse, not the "activation
variable" of an artificial spiking cell. Have you read chapter 10 of The NEURON Book?
