Scientists reveal estrogen’s role in dopamine-driven learning

Researchers at New York University have identified how estrogen shapes learning by strengthening dopamine-based reward signals in the brain. In experiments with rats, learning performance improved when estrogen levels were high and declined when the hormone’s activity was suppressed. The findings, published in Nature Neuroscience, may help explain cognitive fluctuations across hormonal cycles and offer clues to psychiatric disorders linked to dopamine.
