Fourteen healthy subjects received a median nerve stimulation at the left wrist. SEPs were recorded at normothermic baseline (Rest), when esophageal temperature had increased by ~1.2\u00b0C (heat stress: HS) during passive heating, face\/head cooling during passive heating (face\/head cooling: FHC), and after HS (whole body cooling: WBC). The latencies and amplitudes of P14, N20, P25, N35, P45, and N60 at C4\u2032 and P14, N18, P22, and N30 at Fz were evaluated. Latency indicated speed of the subcortical and cortical somatosensory processing, while amplitude reflected the strength of neural activity. Blood flow in the internal and common carotid arteries (ICA and CCA, respectively) and psychological comfort were recorded in each session. Increases in esophageal temperature due to HS significantly decreased the amplitude of N60, psychological comfort, and ICA blood flow in the HS session, and also shortened the latencies of SEPs (all, P &lt; 0.05). While esophageal temperature remained elevated, FHC recovered the peak amplitude of N60, psychological comfort, and ICA blood flow toward preheat baseline levels as well as WBC. However, the latencies of SEPs did not recover in the FHC and WBC sessions. These results suggest that impaired neural activity in cortical somatosensory processing during passive HS was recovered by FHC, whereas conduction velocity in the ascending somatosensory input was accelerated by increases in body temperature. <\/jats:p>","DOI":"10.1152\/ajpregu.00039.2017","type":"journal-article","created":{"date-parts":[[2017,4,12]],"date-time":"2017-04-12T20:30:27Z","timestamp":1492029027000},"page":"R996-R1003","source":"Crossref","is-referenced-by-count":13,"title":["Effects of face\/head and whole body cooling during passive heat stress on human somatosensory processing"],"prefix":"10.1152","volume":"312","author":[{"given":"Hiroki","family":"Nakata","sequence":"first","affiliation":[{"name":"Department of Health Sciences, Faculty of Human Life and Environment, Nara Women\u2019s University, Nara, Japan;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mari","family":"Namba","sequence":"additional","affiliation":[{"name":"Graduate School of Humanities and Sciences, Nara Women\u2019s University, Nara, Japan;
