Epileptics suffer from hyperpolarization of neurons. I’m not a doctor but my friend has this condition and she talks to me a little bit about what happens in her head during a seizure. Her physicians describe it as an electrical discharge in the brain. I guess it’s like an electrical short-circuit of some sort and the brain shuts down. The doctors put her under an EEG machine and start flashing lights at her in order to stimulate the activity, and then they read the brain wave signals from a printout.
