Brain scans and behavioral tests of California sea lions that stranded on shore show how an algal toxin disrupts brain networks, leading to deficits in spatial memory, according to a study to be published Dec. 18 in Science. The new findings by scientists at UC Santa Cruz, ��ϲʿ��ͼ and the Marine Mammal Center in Sausalito, California, suggest that chronic exposure to the toxin domoic acid, produced by naturally occurring marine algae, affects sea lions' ability to navigate in their ocean habitat and survive in the wild.
