bad runs using gcc2.96 with RedHat 7.x

RedHat 7.x series in and about 2000 provided a gnu C compiler version 2.9.6 (aka 2.96) that was apparently not authorized by gnu: http://gcc.gnu.org/gcc-2.96.html October 6th, 2000 It has come to our attention that some GNU/Linux distributions are currently shipping with ``GCC 2.96''. We would like ...

Wang papers

Mike HInes and I ported the Wang and Buzsaki model to Neuron. This model uses the same the continuous connectivity with pointers the you mention. We achieved considerable speed up by moving it over to NetCon's. In general, you cannot expect to see identical network simulations with 2 different integ...

local variable time step with large simulations

With this dense connectivity and large amount of random input, you are likely not getting much benefit from using local variable time step and will prob see faster simulation with the implicit method. On the other hand if you are interested in issues such as synchronization, the implicit method will...

extracellular field generation

Does anyone have code for generating the extracellular field that would be seen by an electrode when running a network simulation? Presumably this could be done by weighting the membrane currents available with extracellular inserted into each section.
