Can you tell me what occurs during an epileptic seizure?

Abnormal discharges: During a seizure there is abnormal electral activity involing a group of discharging neurons. (brain cells) we might be talking about a small part of the cortex of your brain or a large groupe of neurons depending on the type and location. These rapidly discharging cells use up a lot of oxygen, neurotransmitters and nutrients and will stop firing on their own (at least for a while).
