Excel file containing pectoral fin ray afferent responses to pressure. Fin rays were exposed to a series of step-and-hold (0.12, 0.3, 0.6, 1.2, 1.8mm) and ramp-and-hold (1.2, 2.4, 12, 24, 48mm/sec; final amplitude of 1.2mm) pressure stimuli. The hold period during fin ray bending trials was 3s. A burst of action potentials was classified as three or more spikes occurring within 50ms of each other. Each stimulus was divided into several temporal segments (i.e. bins) for analysis. Stimulus segment timing for step-and-hold trials Prestart (0.5s prestimulus baseline), Start (stimulus onset to 1s afterwards), Hold (1.0s to 2.0s), and End (stimulus offset to 1s afterwards). Stimulus segment timing for ramp-and-hold trials: Prestart (0.5s prestimulus baseline), Start (duration of start ramp), Poststart (1s post-start ramp interval), Hold (1s hold interval), End (duration of the end ramp), and Postend (1s post-end ramp interval). Characteristics associated with a burst of action potentials during step-and-hold trials were recorded only during Start and End stimulus segments. Bursts were not always recorded.
