At what temperature does electrical activity in the brain become abnormal?

The correct answer indicates that electrical activity in the brain begins to become abnormal at a temperature of 91.5°F. This threshold is significant because it reflects how hypothermia can affect neurological function. As body temperature decreases, the metabolic and electrical activities in the brain are impaired, leading to abnormal brain activity and potentially resulting in confusion, loss of consciousness, and other serious complications.

Understanding this temperature is crucial for emergency medical technicians since recognizing the signs and symptoms of hypothermia early can make a critical difference in patient outcomes. The brain's normal functioning relies on optimal temperature ranges; deviations can lead to severe consequences for both brain functions and overall health.
