Schizophrenia itself is associated with loss of excitation, but hallucinations and other symptoms of the disorder are caused by a loss of synaptic inhibition.
Researchers find a region of the brain stem called the periaqueductal gray may mediate religiosity and spirituality in humans.
A de novo mutation of SOS1, a gene implicated in Noonan syndrome, may be implicated in sudden infant death, researchers report.
Opioid use disorder affects genes associated with proinflammatory immune molecule encoding and genes associated with remodeling the extracellular matrix, suggesting the connection between neurons may be altered as a result of opioid use. Additionally, …
The recently discovered Homo longi lineage may be our closest relative. The findings have the potential to reshape our understanding of human evolution.
Taking SSRI antidepressants does not increase the risk of developmental delays or autism in children, a new study reports. However, there is an increased risk for ASD and developmental delays in children whose mothers suffer from maternal psychiatric d…
A twenty-year study has identified an association between childhood depression and an increased risk of physical and mental health problems as adults. Researchers found those with childhood depression had a greater risk of anxiety, substance use disord…
Functional connectivity was reduced within and between several brain networks in children raised in disadvantaged neighborhoods. Researchers say a positive home and school environment can mitigate some of the effects.
Peripheral and brain markers for fear differ in a hormone dependent manner between males and females.
Researchers have identified novel neurocircuitry between midbrain structures which are modulated by leptin to control eating behaviors in mice.
Anabolic androgenic steroids, drugs commonly associated with muscle building and enhancing athletic performance, are known to increase the risk for certain health disorders. A new study reveals anabolic steroids may also accelerate brain aging.
Somatic gene mutations in brain cells could account for some of the pathology of schizophrenia.
A two-week course of CBD helps normalize and restore the function of two proteins associated with reducing amyloid-beta accumulation in mouse models of familial Alzheimer’s disease. CBD also reduces levels of IL-6, an immune protein associated with inf…
Enzyme activity outside of specific cell types contribute to synaptic plasticity associated with addiction behaviors.
Infant children whose mothers experienced neglect when they were young showed altered brain circuitry in areas associated with anxiety and fear response.
Smaller brain volumes in the cingulate cortex, insular, and superior frontal cortex predict an increased likelihood of developing PTSD three months after brain injury.
Children with autism show a significant increase in IQ scores between the ages of 12 and 23. Those with the greatest increases in IQ scores had early regressions in language and communication skills by the age of 12.
Sleep deprivation reduces the brain’s ability to unlearn fear-related memories, a new study reports.
Astrocytes respond to cocaine exposure in the brains of mice by promoting the formation of new synapses.
Women, especially minority women, from states with more restrictive reproductive rights have a greater risk of delivering a low-weight baby and face more health disparities than women who reside in states with fewer restrictions on reproductive rights.
