Topic: tactile stimulations

Real world information received by sensory systems is highly dynamic. If and how the recent temporal dynamics, as in the preceding intervals, shape cortical processing is unclear. Here we recorded the cortical signals (EEG) in response to a dynamic train of tactile stimulations applied at the fingertips ( n = 64). We separated the cortical signals according to the next interval dynamics by using a joint-interval distribution (JID) spanning 100ms to 10s. This yielded a two-dimensional event-related potential (JID-ERP) at all the examined time points of the EEG signal (-200 to 300 ms latency fro
