A new study reports that abnormalities in the SOD1 protein are a common factor in all types of motor neuron diseases.
Gene expression in male and female brains becomes more similar due to age, and both sexes contribute to the pattern. If the expression of a gene is higher in younger female brains it tends to be lower in younger male brains. Due to age, the gene expression reduces in females and increases in males, and vice versa.
Addiction may not always be a fixed personality or genetic trait, instead the result of our plastic brains learning the effect of drugs on our individual responses and the environmental setting in which the substance is used.
Researchers identified a pathway that begins in the gut and ends with a pro-inflammatory protein in the brain that appears to contribute to the development and progression of Alzheimer's disease.
Circadian rhythm disruption plays a critical role in weight gain, a new study reports.
A study of combo jellies reveals the type of messenger that likely functioned in the ancestral nervous system.
The effects of COVID-19 infection on neurological health are becoming more apparent. A new study reveals COVID-19 can predispose people to irreversible neurological conditions, accelerate brain aging, and increase the risk of stroke and brain bleeds.
The VMAT1 gene evolved through natural selection in human evolution. Those with the Ile-type variant of the VMAT1 gene are less prone to anxiety and depression.
Microglia that express the Alzheimer's associated APOE4 genetic variant are unable to effectively metabolize lipids. This causes lipids to build up, promoting inflammation and preventing effective neurotransmission.
A new large-scale genome-wide study has identified 18 new genetic risk factors for opioid use disorder, bringing the number of OUD-associated genes from 1-19.
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.
Researchers discovered a new set of chemical reactions that use cyanide, ammonia, and carbon dioxide generates amino acids and nucleic acids, the building blocks of proteins and DNA.
