Hot or cold? How the brain deciphers thermal sensations

Thermal sensations are consciously differentiated as hot or cold by the brain; however, the neural mechanism that enables this differentiation is not well understood. To address this, researchers have used electroencephalography to record brain activity during hot or cold stimuli. They found that while both temperatures activate the same ten cortical regions, their patterns of EEG across frequencies differ, influencing behavior. These findings contribute to developing objective methods for evaluating thermal comfort.
