In the news
The article mentions electrophysiology alongside other laboratory methods to confirm that brain cells were being functionally recruited during drug treatment. It serves as evidence that the neurons were actively participating in the body's metabolic response.
Scientists assumed semaglutide’s long-term effects would depend on silencing the brain’s hunger neurons. But a Yale-led study published in PNAS in August 2026 found that prolonged treatment recruited these neurons in female mice—and disrupting them w
