The California Fish and Game Commission has banned crab fishing until further notice after detecting high levels of a neurotoxin in Dungeness and rock crabs. The toxin, domoic acid, is produced by certain types of planktonic algae, and it becomes concentrated in tissue of crabs and other marine organisms during plankton blooms. People who consume sufficient quantities of the toxin develop amnesic shellfish poisoning, so named because it kills neurons in a part of the brain that is critical for memory. Here’s how it works.

A rush of adrenaline flushes through your blood setting your heart pounding and muscles twitching, but there is nothing left to do. Your brain’s rapid response defense system has already detected the threat and avoided it before your conscious mind is even engaged. How is that possible, scientist, Peng Cao and colleagues of the Chinese Academy of Sciences wondered?
