Link found between estrogen, changes in brain structure, and learning and memory

Scientists have discovered how estrogen initiates physical changes in rodent brain cells that lead to increased learning and memory — a finding, the researchers contend, that illustrates the likely value of the hormone to enhance brain functioning in women. Their study, published in the March 15 issue of The Journal of Neuroscience, describes for the first time a chain of molecular events that is activated in the brain’s primary memory center, called the hippocampus, when estrogen bathes nerve cells.
