Neck Cooling as a Non-Invasive Method to Lower Brain Temperature in Healthy Adults

Cold water was circulated through an adhesive wrap applied to the front of the neck, overlying the carotid arteries, for 120 minutes. MR thermometry was used to measure core brain temperature in 1-minute intervals throughout the intervention. On a different day, subjects crossed over and repeated the intervention in the other study arm (i.e., cold went to body-temperature, and vice-versa).
