Rationale: The perception of tactile texture supports the exquisite ability of the somatosensory system to track vibrations elicited at the level of the skin when sliding against a surface. Whether the primary somatosensory cortex (S1) is able to encode the fine-grained spectrotemporal features distinguishing textures remains unknown. Methods: To address this question, we performed an oddball experiment in which 40-second vibrotactile sequences consisting of standard stimuli (A) and oddball stimuli (B) were presented in an AAAAB pattern, with a base presentation rate of 8 Hz and an oddball presentation rate of 1.6 Hz (8/5). EEG frequency-tagging was used to identify and characterize the responses to vibrotactile oddball contrasts. In a first session, A and B were pure sinusoidal vibrations differing in frequency and intensity, that were used to construct an EEG functional localizer of responses originating from the hand and foot representations in S1. In a second session, A and B were two different snippets of bandpassfiltered white noise matched in terms of intensity and average frequency content, but differing in terms of their complex spectrotemporal content. Results: Significant base and oddball responses were recorded for both conditions and stimulation sites. Using the functional localizer constructed from base responses to hand and foot stimulation using the frequency/intensity sequences, we showed that oddball responses to spectrotemporal contrasts followed the somatotopical organization of S1. Discussion: In conclusion, we show that encoding of fine-grained spectrotemporal features distinguishing vibration patterns produced by scanning different textures involves S1.
