The time course of sensory adaptation in the cockroach tactile spine.
Power-law dynamics have been widely used to fit the adaptation of sensory receptors, including the cockroach tactile spine. We used a new log-binning technique to re-examine step responses in the tactile spine. The power-law only fitted responses over a restricted time period, while a sum of three exponential decays gave an accurate fit over the entire response duration.
