During alarm reaction, which brain region receives the distress signal to increase energy?

• A. Cerebellum
• B. Hypothalamus
• C. Frontal Lobe
• D. Occipital Lobe

Answer: (B)

During alarm reaction, the brain region that detects distress signals and mobilizes energy is the hypothalamus. It acts as the command center that, upon perceiving threat from limbic structures like the amygdala, activates both the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. This leads to the release of adrenaline and cortisol, increasing glucose availability, heart rate, and overall energy to prepare for fight or flight. The cerebellum handles movement coordination, the frontal lobe handles planning and decision making, and the occipital lobe processes visual information, none of which rapidly mobilize energy in response to danger.
