Researchers aim to map and track cellular changes in the human brain over a lifetime.
Significantly worse symptoms of depression, anxiety, and loneliness were seen in younger people, while older people showed greater mental well-being. However, when it came to cognition, task performance was worse in older adults.
Neurons in the suprachiasmatic nucleus coordinate to adapt to different lengths of daylight, changing at cellular and network levels. The neurons changed in mix and expression of dopamine, altering brain activity and subsequently daily routine behaviors.
Higher rates of light physical activity and moderate-to-vigorous exercise were associated with a lower risk of death. Sedentary lifestyles were associated with a higher risk of death. The findings were consistent among women with different levels of genetic predispositions to longevity.
Those with hereditary hemochromatosis who have two copies of the gene mutation that cause the disorder have an increased risk of developing movement disorders including Parkinson's disease.
Accelerated biological and epigenetic aging was associated with lower odds of older women living to the age of 90 and beyond.
Researchers have identified a set of genetic mutations that protect against cognitive decline in older adults. A new study suggests the selective pressure from infectious pathogens like gonorrhea may have promoted the emergence of this genetic variance in Homo sapiens.
Mindfulness meditation interrupted communication between brain areas involved in processing pain sensations and areas that produce the sense of self. This resulted in reduced pain as individuals lost ownership of the sensation.
Ripples occur in the human cortex, both while we are awake and asleep.
People who intentionally hurt others because they believe they are morally right or justified, do not respond rationally to material benefits, a new study reports. Researchers say those who punish others to signal their own "moral goodness" may be more likely to question their claims of moral righteousness when judged negatively by their peers.
Six months following COVID-19 infection, two-thirds of patients still experienced neurological symptoms including headaches, memory impairment, and decreased concentration that impacted their quality of life.
Genetic factors influence the severity of symptoms in children on the autism spectrum, and different genetic factors were associated with different symptoms of ASD.
