The air we breathe may be seeding our brains with toxic proteins. A landmark study reveals a direct link between fine particulate pollution and the harmful protein buildup seen in Lewy body dementia, a common neurodegenerative disease.| PsyPost – Psychology News
A new study shows the type of feedback a chatbot gives affects learning and brain activity. Reflective feedback boosts problem-solving, while encouraging feedback improves memory.| PsyPost – Psychology News
Drinking blackcurrant juice boosts blood circulation in a brain region linked to attention and decision-making, according to a new study in Nutritional Neuroscience.| PsyPost – Psychology News
Psychological stress can impair the brain’s reward system, contributing to psychiatric disorders. A new study examines how a key hormone, often overlooked in males, may provide a natural defense against the behavioral consequences of stress and social challenges.| PsyPost – Psychology News
Scientists have developed a chemogenetic tool that boosts mitochondrial activity in the brain, reversing memory loss in mouse models of dementia. The findings suggest that impaired energy production in brain cells may directly contribute to cognitive decline in neurodegenerative diseases.| PsyPost - Psychology News
Even in deep sleep, your brain doesn’t completely tune out. New research reveals that while sound processing in the cortex fades as sleep deepens, the brainstem keeps listening—providing insight into how the brain balances rest with environmental awareness.| PsyPost - Psychology News
New research suggests "neural confusion" may underlie social avoidance in some forms of autism. In a mouse study, neurons that should value social contact responded similarly to both another mouse and a plastic object, blurring the line between the two experiences.| PsyPost - Psychology News
In a breakthrough for addiction science, neurobiologists have pinpointed the precise brain circuit that suppresses the urge to binge drink. This discovery of the brain's own "off switch" could revolutionize how we understand and treat alcohol use disorder.| PsyPost - Psychology News
Researchers identified a brain circuit in mice that triggers safety-seeking movement, overriding drives like hunger and social interaction. This lateral hypothalamus to brainstem pathway activates context-dependent locomotion toward shelter in response to internal or external threat cues.| PsyPost - Psychology News
