    TWiN 66: Neuroscience of overeating
    Nov 26 2025

    TWiN reviews the underlying neurobiological mechanisms of overeating and obesity, the role of the hypothalamus and reward systems in controlling food intake and energy balance, and how dysregulation in these systems leads to overeating.

    TWiN 65: Air pollutants promote dementia
    Nov 4 2025

    TWiN explains epidemiological data showing that exposure to air pollution was associated with an increased risk of developing Lewy body dementia, and nasal administration of air pollution in mice led to brain atrophy and impaired cognition and motor function.

    TWiN 64: How the brain decides what we see
    Oct 8 2025

    TWiN explains how visual neurons show functional flexibility by selectively responding to subsets of inputs representing attended objects while ignoring those conveying information about irrelevant objects.

    TWiN 61: Blood to the brain
    Jun 25 2025

    TWiN reveals that proteins travel from the blood to the brain where they are taken up by microglia, revealing a new mode of communication between the brain and the periphery.
