PMID-17419757[0] Detection psychophysics of intracortical microstimulation in rat primary somatosensory cortex.
- headposted rats, ICMS to barrel cortex
- single pulse threshold = 2 nC, around the threshold for evocation of short-latency action potentials near an electrode.
- one pulse saturated at 80% correct.
- multiple pulses had a higher rate, though this saturated at 15 pulses.
- double pulse optimal in terms of power / discrimination.
