Question

Quizplus · Accepted Answer

Paroxysmal depolarizing shifts (PDS) are transient changes in neuronal membrane potential that cause synchronized bursts of excitation in a group of neurons. They are a hallmark of epileptic activity and are commonly seen in the EEG of patients experiencing partial seizures. PDS are not typically seen in tonic-clonic or absence seizures, and there is no established link between PDS and migraine headaches.
