spike_times.m

Detection of location of spike times

Description

   This function detects and locates the time points of action potentials in a trace of membrane potential as a function of time in a neuron. The trace should represent a current clamp recording from a neuron.

   Input:
   "trace" is the membrane voltage array of the neuron "threshold" is the factor times the maximum membrane potential (peak of spike) This "threshold" factor should be between 0 and 1 and the default value is 0.5

  Output:
  The output array is the index location of spikes.
