Calcium, Honeybees, Memory

Long-term memory formation in honeybees is instigated by a calcium ion cascade. Researchers have shown that calcium acts as a switch between short- and long-term storage of learned information.

Jean-Christophe Sandoz led a team of researchers from the CNRS, the Université de Toulouse and the French Calcium Research Network, who carried out the neurological honeybee experiments. Sandoz and his colleagues studied a learned behaviour in the bees, extension of the proboscis in response to olfactory stimuli associated with food. Three days after decreasing calcium levels during learning, the bees stopped responding to the odor, and three days after increasing calcium during learning, bees' response to the odor were stronger. In addition, the researchers found that the increased memory performance in bees induced by increased calcium depended on protein synthesis. According to Sandoz, "We have found here that the modulation of calcium during learning affects long-term memory specifically while leaving learning and short-term memory intact".

I (Glen) wonder if this applies to our memory also?
