Researchers have identified a brain protein that acts like a personal trainer, pumping up pathways essential for memory.
The study in rats out of Northwestern University identifies the protein Kalirin as a memory booster. Researchers found this protein strengthened the communication lines between brain cells. The more often a task was repeated the stronger the lines became.
Previous studies have found patients with Alzheimer's disease lack the protein. Researchers say this explains why continued learning plays a role in delaying the disease.
Kalirin strengthens the synapses between cells. The synapses grow stronger the more often a task is performed.
