Force sensor in simulated skin and neural model mimic tactile SAI afferent spiking response to ramp and hold stimuli.

As magnitude of stimulus hold increased, for indentation types III , IV , and V (1.2, 1.3, 1.4 mm respectively), mean first spike latencies (± SD) were not different for those predicted by the spiking-sensor (154.96 ± 3.17, 155.525 ± 4.55, 159.055 ± 5.86 ms) although they exhibited an increasing trend.

Considering first spikes, the predicted latencies exhibited a decreasing trend as stimulus rate increased, as is observed in afferent recordings.
