Computer model of clonazepam`s effect in thalamic slice (Lytton 1997)
Accession: 12631
Demonstration of the effect of a minor pharmacological synaptic change at the network level. Clonazepam, a benzodiazepine, enhances inhibition but is paradoxically useful for certain types of seizures. This simulation shows how inhibition of inhibitory cells (the RE cells) produces this counter-intuitive effect.

Note: This model only runs under UNIX (and linux) for the
current version of neuron (5.2).  Future versions of neuron for the
mac and pc will be able to run this model.

This simulation is very similar to the one published in the paper
  but is not identical due to variations among randomizers using
  supposedly identical algorithms.  The original was run under Sun
  Solaris.  The example files included here were produced under
  Intel Linux.  I have chosen traces from the current runs that are
  very similar to those in the publication.  However, these specific
  traces may not look identical if a different randomizer is used.
  I also graph all 64 traces from the network so that they can all
  be looked at and compared to the figure.

* COMPILE and RUN:
  nrnivmodl
RUN: 
  $CPU/special init.hoc -

* TO JUST LOOK AT PRE-SAVED DATA
  $CPU/special disp.hoc -

to look at your newly run data later modify disp.hoc line 23

20110411 changed euler solve method to cnexp in IAHP_destexhe.mod
