UCLA/Toronto researchers unlock key to memory storage in brain Study suggests new approach for treating Alzheimer's, brain injury

摘要

Scientists know very little about how the brain assigns cells to participate in encoding and storing memories. Now a UCLA/University of Toronto team has discovered that a protein called CREB controls the odds of a neuron playing a role in memory formation. The April 20 edition of Science reports the findings, which suggest a new approach for preserving memory in people suffering from Alzheimer's or other brain injury. "Making a memory is not a conscious act," explained Alcino Silva, principal investigator and a professor of neurobiology and psychiatry at the David Geffen School of Medicine at UCLA. "Learning triggers a cascade of chemicals in the brain that influence which memories are kept and which are lost.
