Binge drinking affects memory.
The study found that healthy young students who engaged in heavy drinking required more attention to complete a given task.
When memory is stored in the brain, the connections between nerve cells, called synapses, change. Strong memories are formed when synapses become stronger through structural changes that occur at the synapse. PKC-alpha works with glutamate and norepinephrine to create those changes.

Oxygen treatment hastens memory loss in Alzheimer's mice
Tampa, FL (Aug. 11, 2009) -- A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery – a hypothesis borne out in a recent animal model study.
