Scientists are researching exactly how heat impacts brain function and seizure activity so they can find solutions. FutureNeuro Research Ireland Centre for Translational Brain Science has observed a disturbing trend in brain cells that are particularly sensitive to temperature. The ILAE is a global organization through which clinicians and scientists join forces to gauge the impact of climate change on brain function. “From recording brain cell activity, we know that as you get above this temperature, brain cells start to behave differently and just fire synchronously, which is what happens during a seizure,” said Henshall. “It is very disruptive to brain function when they all fire together.
