TO THE EDITOR: Middle cerebral artery blood velocity (MCAV mean) is reduced up to 30% in humans following a passive increase in internal temperature of 1–1.5°C (1). If the diameter of the MCA remains unchanged during heat stress, reductions in MCAV mean are proportional to reductions in cerebral blood flow. In support of selective brain cooling in(More)
Decrease of the human brain temperature was induced by intranasal cooling. The main purpose of this study was to compare the two magnetic resonance methods for monitoring brain temperature changes during cooling: phase-difference and magnetic resonance spectroscopic imaging (MRSI) with high spatial resolution. Ten healthy volunteers were measured. Selective(More)
