Our human brain performs a variety of activities and functions throughout the day. The temperature of human brain keeps changing throughout out the day. Now, according to new research, the normal temperature of the human brain swings significantly more than previously assumed, and this could be an indication of good brain function. The study states that some areas of the deep brain can reach temperatures of up to 40 degrees Celsius, albeit this varies depending on sex, time of day, and other factors. When compared to this, the average oral temperature in humans is normally less than 37 degrees Celsius. [1]

Figure 1 shows using a brain scanning tool called magnetic resonance spectroscopy, researchers were recently able to detect brain temperature in healthy persons (MRS). However, till now, MRS had not been utilized to investigate how brain temperature varies during the day, or how one’s ‘body clock’ influences this.

The new study is the first to build a 4D map of healthy human brain temperature. By displaying how much brain temperature changes by brain area, age, gender and time of day, this chart disproves a number of previously held ideas. [2]

Temperature rhythms in injured brains

To explore the clinical implications of data obtained from healthy volunteers, the researchers analysed temperature data collected continuously from the brain in 114 patients who had suffered from moderate to severe traumatic brain injury (TBI). The patients' average brain temperature was 38.5°C, but it varied even more widely, from 32.6 to 42.3°C.

Of 100 patients for whom there was enough data to test for daily rhythms, only a quarter had a daily rhythm in brain temperature. [3]

"That a daily brain temperature rhythm correlates so strongly with survival after TBI suggests that round-the-clock brain temperature measurement holds great clinical value," says neurologist Nina Rzechorzek from the MRC Laboratory for Molecular Biology. [4]>
