Interactive contributions of intracellular calcium and protein phosphatases to massed-trials learning deficits in Hermissenda.

abstract：:Anterograde amnesia (AA), forgetting of events that occur following a traumatic episode, has recently been demonstrated by using a mild decrease in temperature (hypothermia) as the amnestic agent. However, no data currently exist to indicate if an increase in body temperature (hyperthermia) might affect memory process...
