Episode 26: The Neuroscience of Seizures and Epilepsy

Neuroscience: Amateur Hour

Hello! I return!
Today we will be talking about the neuroscience of seizures and epilepsy. Brought about an imbalance of the accelerators (excitatory circuits) and brakes (inhibitory circuits) of the brain, seizures are pretty terrifying events. They're marked by temporary confusion, a staring spell, uncontrollable jerking of the arms and legs (like what you see when someone depicts a seizure on gray's anatomy), loss of consciousness, or even some cognitive and emotional symptoms. Curious to find out what the heck the brain is up to during seizures? Come and listen to find out more!
