#EstrousCycle

A groundbreaking new study reveals that the natural ebb and flow of hormones during the reproductive cycle can dramatically reshape the brain and sharpen learning abilities, promising to transform our understanding of cognition—and even hinting at new paths in personalized medicine. Published this week in the journal Neuron and led by researchers at the University of California, Santa Barbara, the research shows that cyclical changes in estrogen not only alter the physical structure of neurons in the memory-related hippocampus but also enhance the brain’s ability to form and maintain mental maps of our surroundings (Neuroscience News).
