Brain Pathway That Shuts Down Seizures Identified

Researchers have uncovered a brain pathway that shuts down seizures. They found that an acid-activated ion channel in the brain reacts to a drop in pH (increased acid) in a way that shuts down seizure activity. The link between low pH in the brain and seizure termination was first hinted at nearly 80 years ago when clinical experiments showed that breathing carbon dioxide, which makes brain tissue more acidic, helps stop epileptic seizures.
