![]() ![]() Since activity in wires produce heat, all electric and magnetic stimulation of the brain deposits thermal energy in the brain. Steven Schiff, MD, vice chair for global health in Neurosurgery at Yale School of Medicine, specializes in the intersection between engineering and neurosurgery, which gives him the background to apply principles of physics to the biological processes of the brain. ![]() In a paper published in the Journal of Neural Engineering, researchers found that small increases in temperature while stimulating the brain can profoundly alter brain activity, sometimes with negative consequences. Researchers now know that the physics behind this environmental phenomenon apply also to brain activity. Heat a Siberian peat bog faster than it can release carbon into the atmosphere, and you get a wildfire on your hands – even in subzero temperatures. These environmental phenomena demonstrated a basic principle of physics – temperature is one of the main components of a chemical reaction and even seemingly small changes can result in catastrophic impacts. They were caused in part by rising global temperatures, which accelerated the ability of bacteria in the soil to metabolize plant and animal matter. ![]() Last summer, devastating wildfires raged across frozen regions in Siberia, Alaska, and Canada. ![]()
