Measuring oddball responses to vibrotactile textures
Résumé
Using a fast-periodic oddball paradigm, together with EEG frequency-tagging, we aimed to assess the possibility of measuring periodic responses to rapid changes in a vibrotactile texture. Sequences consisting of standard (A) and oddball stimuli (B) were presented in an AAAAB pattern, with a base and oddball presentation rate of 8 Hz and 1.6 Hz (8/5 Hz), respectively. A and B stimuli either differed in frequency and intensity, or in terms of their complex spectrotemporal composition. Preliminary results suggest that the protocol can be successfully used to record EEG correlates of the cortical processing of haptic textures.
