Options
  • duration (number, ms): Duration of stimulus.
  • preduration (number, ms): Duration of preadapting stimulus.
  • pause (number, ms): Pause between successive stimuli.
  • delay (number, ms): Part of pause before stimulus.
  • maxintfac (number): Maximum intensity factor.
  • minintfac (number): Minimum intensity factor.
  • nints (integer): Number of stimulus intensities.
  • maxpreintfac (number): Maximum intensity of preadapting stimulus.
  • minpreintfac (number): Minimum intensity of preadapting stimulus.
  • npreints (integer): Number of preadapting intensities.
  • repeats (integer): Number of repetitions.
  • blockrepeats (integer): Number of repetitions of an intensity sequence.
  • singlerepeats (integer): Number of immediate repetitions of each intensity.
  • medres (integer): Medium resolution.
  • nskip (integer): NSkip.
  • minrateslope (number, Hz/mV/cm): Minimum slope of f-I curve.
Files
  • fispikes#.dat : the spikes of trace #.
  • firate.dat : the firing rate.
  • ficurve#.dat : Summary of f-I curve data of trace #.
Plots
  • f-I curve : baseline activity (blue), prestimulus rate (orange), onset rate (green), steady state (red)
  • firing rate : spikes (red), firing frequency (yellow), stimuli onsets (white)
Requirements
  • Transdermal EOD recording (EODTrace2) and events (EODEvents2).
  • One or more spike events (SpikeEvents[*]).
