Electrically evoked changes of rat spinal neurones following UVB irradiation

A, electrically evoked responses of rat WDR neurones with electrical stimulation illustrating the convergent afferent input of recorded cells (Aβ-fibres, Aδ-fibres and C-fibres) and measures of excitability (post-discharge, input and wind-up). Only input was significantly enhanced with UVB irradiation (unpaired t test, **P < 0.01). B, C-fibre thresholds of second order neurones in UVB rats is lower compared to naive rats (unpaired t test, **P < 0.01).
