Summary: Researchers have developed a new kind of artificial neuron—called infomorphic neurons—that can independently learn and self-organize with nearby neurons, mimicking the decentralized learning of biological brains. Inspired by pyramidal cells in the cerebral cortex, these neurons process local signals to adapt and specialize in tasks without external control.Each infomorphic

Summary: New research uncovers how dopamine in the ventral shell of the nucleus accumbens (vsNAc) governs the sexual behavior sequence in male mice, from sniffing to ejaculation. Using fiber photometry, scientists identified rhythmic dopamine activity during intromission that aligns with movement patterns and is regulated by acetylcholine inputs.Crucially, the final

Summary: For the first time, researchers have directly observed dopamine release in the human brain during moments of cognitive flexibility. Using PET imaging, they found that dopamine levels spike in the ventromedial prefrontal cortex when people switch between tasks — and the more dopamine released, the more efficiently they adapted.This

Summary: A large study of over 14,000 Norwegian veterans reveals that taking a life in combat doesn’t automatically damage a soldier’s mental health—context matters. Veterans from Afghanistan, where combat was expected and rules of engagement were clear, showed no long-term psychological harm from killing.In contrast, Lebanon peacekeeping veterans who had

Summary: A new study reveals that long-term high-fat diets reduce pleasure from eating by lowering neurotensin, a brain peptide that boosts dopamine response. This loss of reward dampens the desire for high-calorie foods, potentially worsening obesity by promoting habitual, joyless eating.In mice, restoring neurotensin levels reversed this effect, improving weight

Sumary: A new study reveals that young mothers who feel emotionally connected to their unborn babies are more likely to form healthy, positive relationships with their children later. Researchers tracked 160 racially diverse, low-income mothers from pregnancy to their child’s toddler years, showing that prenatal bonding plays a key role
