The influence of calcium on short-term memory.
Using a passive avoidance behavioural task in day-old chickens, it is possible by intracranial injection of appropriate drugs to separate out three phases of memory formation. The duration of the first such phase, called short-term memory, is increased when the intracranial calcium ion concentration is raised and the phase is practically abolished by injection of lanthanum ions.
