repetitive firing neuron

Post by Johannes » Wed Jun 15, 2005 1:07 pm

Hi,

What would be the best way to implement a neuron (not necessarily a biophysical cell) that fires repetitively in the absence of any stimuli, but can increase or decrease its firing frequency upon receiving excitatory or inhibitory synaptic input, respectively?
I was thinking about using an IntFire1 cell, but if I understand it correctly, this type of cell needs to be driven by a constant NetStim input in order to fire repetitively. I don't really want this constant input.
Any suggestions?
Thanks, Johannes

"Best" depends on the details of what you want to use it for.
It turned out that your own application would be satisfied by an artificial
spiking cell (integrate and fire neuron). IntFire2, which is built into NEURON,
does what you want, although it is somewhat limited in that inhibitory and
excitatory inputs to it elicit responses that have identical kinetics.
