Action potential data from the somato-sensory pathway

Vibration of whiskers activates mechanoreceptors in sinus hair follicles. Neurons of the thalamic ventrobasal complex (VB) receive glutamatergic excitatory inputs from the principal trigeminal nucleus and primary somatosensory cortex. The thalamic reticular nucleus (TRN), activated by collaterals of thalamocortical projections, provides GABAergic inhibitory feedback. The experiments addressed to the somatosensory pathway show an exquisite sensitivity to vibratory stimuli with 1:1 responses up to high frequencies and phase-locking precision in the sub-millisecond range.
