Sensory flow in the DLS and S1. a Micrographies show the site of injection of Fluorogold in the DLS (left), stained cells in the thalamus, including the VPL (right). b Schematic view of the site of recordings and histological confirmation of the silicon probe position in S1 and DLS. c Activity of eight illustrative units aligned to the stimulation onset of the forelimb contralateral to the recording site. Spike rasters (top) and average peri-event histograms (bottom) are depicted for cells with different response patterns recorded in S1 (left column) and DLS (right column). d Averaged firing rates for cells recorded in S1 (top) and DLS (bottom) expressed as Z-score (color coded) and sorted according to the time they reached the highest activity after stimulus onset. Histograms of the response latencies for all cells recorded in S1 (e) and DLS (f); for better appreciation, insets display latencies shorter than 60 ms. g Overlap of latency distributions in both regions. h Comparison of the response latencies for the entire population of cells (left) and for the cells with latencies shorter than 30 ms (right)
