These neuronal models were used for the following papers: Shu Y, Duque A, Yu YG, McCormick DA. Properties of action potential initiation in neocortical pyramidal cells: evidence from whole cell axon recordings. Journal of Neurophysiology. 97: 746-760, (2007). Shu Y, Hasenstaub A, Duque A, Yu Y, McCormick DA (2006) Modulation of intracortical synaptic potentials by presynaptic somatic membrane potential. Nature 441: 761-765. --- The model pyramidal cell with full dendritic tree and axon arbor is for simulating the action potential generation process of pyramidal cells in layer V of prefrontal cortex. code: best_full_axon_decay.hoc This code is used to calculate the spacial decay constant of main axon. code: best_full_axon_spike_init.hoc This code is used to calculate the initiation point of action potential in axon initial segment. Notice: After running code, output data file is saved in a file called "seg.dat" which can be analysized by the matlab code 'for_decay.m', and 'for_initiation.m'. These model files were contributed by: Yuguo Yu Yale University yuguo.yu@yale.edu 20111026 cad.mod capump.mod ih.mod release.mod updated to use derivimplicit method. See files for more details.
