In this captivating episode, we explore domoic acid, a fascinating neurotoxin produced by marine diatoms that has earned notoriety for causing amnesic shellfish poisoning. Through detailed molecular analysis, we'll uncover how this powerful compound mimics glutamate, a crucial neurotransmitter in the brain, leading to devastating neurological effects. Expert interviews will reveal the intricate mechanisms by which domoic acid overstimulates glutamate receptors, causing calcium overload in neurons and potentially permanent memory loss. We'll investigate how this toxin accumulates in shellfish and travels up the marine food chain, affecting sea mammals and humans alike. Our journey will take us through research facilities where scientists are studying this remarkable compound to better understand both its toxic effects and potential applications in ...
