Researchers identified specific receptors for acetylcholine that reroute information flow through memory circuits in the hippocampus. The findings could have implications for the development of drugs to help enhance or protect memory from diseases associated with cognitive decline.
Study reveals a link between corticosteroid receptors and genes associated with ciliary and neuroplasticity in the hippocampus, an area of the brain associated with stress response, learning, and memory.
Children who reported higher levels of school enjoyment at age six score, on average, 14.4 more GCSE exam points at age 16, and were 29% more likely to gain five or more A* - C grades than those who reported lower enjoyment at school.
Flies without the Rim gene or cac Cav2 channel function displayed numerous cognitive and behavioral deficits associated with schizophrenia, and had reductions in synaptic growth and neural calcium transients. Exposing the flies with Rim deficits to the common antipsychotic haloperidol reduced some of the schizophrenia-related behavioral symptoms.
Administering memory tests over four weeks to older adults may help to predict those most at risk for developing Alzheimer's disease.
Specific genetic mutations affect both the existence and amount of particular bacteria in the gut.
Children whose mothers consumed alcohol at 18 weeks of pregnancy were 17% more likely to be diagnosed with depression at age 18 compared to those whose mothers abstained from drinking.
The link between smoking, depression, and schizophrenia is due, in part, to a causal effect of tobacco use. Findings reveal that smoking increased the risk of schizophrenia and depression. Additionally, depression and schizophrenia increased the likelihood of a person becoming nicotine dependent.
In addition to being detrimental to general health, heavy smoking has a causal effect on facial aging. Heavy smoking affects facial attractiveness and spurs earlier and increased skin wrinkling.
Study finds an association between acetaminophen use during mid-to-late pregnancy and increased risk of hyperactivity, attention problems, and other behavioral deficits in young children. Boys appear to be more susceptible to the adverse effects acetaminophen use during pregnancy. However, the negative effects only seem to persist during the early years of life.
