Brain temperature as a function of depth and effect of perfusion with warmed ACSF. A: repeated measurement of brain temperature as a function of depth into the brain with no perfusion (blue lines) and during perfusion of the brain surface with warmed ACSF (at 37.4 ± 1.3°C; red). Four depth profiles were measured sequentially by pushing the thermocouple into the brain, with no perfusion, perfusion with warmed ACSF, no perfusion, and perfusion with warmed ACSF. Room temperature was 23–24°C. B: brain temperature as a function of depth, shown schematically, in the absence and presence of surface perfusion with warmed ACSF.
