Summary: Researchers identified disease-specific reductions in emotional expressivity in Lewy body dementia through deep neural network analysis. This reduced vocal expression is linked to cognitive impairment...
Summary: Long COVID, affecting 7% of U.S. adults, often includes debilitating brain fog. Symptoms like forgetfulness and difficulty focusing affect daily life and work. A new...
Summary: Researchers suggest that the type of estrogen in hormonal birth control influences anxiety-like behaviors. Researchers found that synthetic estrogen in birth control led to increased...
Summary: Fruit flies use the neurotransmitter octopamine to decide whether food memories are stored long-term or short-term. This process, influenced by energy reserves, affects future eating...
Summary: Staying up late harms mental health regardless of one’s natural sleep preference. Surveying nearly 75,000 adults, researchers discovered that both morning and night types who...
Summary: A new study uncovers a key biological process targeted by SSRIs, suggesting new clinical applications. The study found that SSRIs affect membrane trafficking in cells,...
Summary: Following a Mediterranean diet reduces the risk of all-cause mortality by 23% in U.S. women over 25 years. The diet’s benefits include lower cancer and...
Summary: Stimulating the brain’s serotonin center, the dorsal raphe nucleus (DRN), activates areas responsible for behavior and motivation. This discovery, using opto-functional MRI in awake mice,...
Summary: As we age, our brain naturally becomes more insulin resistant, disrupting neuron communication and leading to cognitive decline and neurodegeneration. Researchers studied how acute insulin...
