parallel computation of extracellularly evoked potentials
Posted: Wed Sep 24, 2008 11:52 am
Dear all,
I have a population of neurons and an extracellular current source to be simulated. Neurons are not connected each other, they are instances of the same model but use different values of the parameters. I would like to simulate the population on a cluster and periodically (e.g., once every 40 time steps) perform the following actions:

I would like to simulate the population on a cluster and periodically (e.g., once every 40 time steps) perform the following actions:
- computing the extracellular potential globally evoked by the whole population in a given geometrical point;
using the value of the evoked potential to update the amplitude of the extracellular current (feedback control);
updating the extracellular potential at the cellular membranes as a consequence of the new extracellular current amplitude.
