Researchers find key to keep working memory working

Acetylcholine helps muscarinic M1 receptors in the prefrontal cortex to maintain information in working memory. As acetylcholine actions at M1 receptors are reduced in conditions which affect working memory, such as schizophrenia and Alzheimer's disease, researchers report the M1 receptor may serve as a potential therapeutic target to restore working memory.

Schizophrenia risk gene linked to cognitive deficits

SETD1A, a gene associated with schizophrenia, stunts the growth and branching of dendrites and reduces the number of dendritic spines. Reinstating the normal expression of SETD1A in mouse models restored working memory function.

Exposure to air pollution before and after birth may affect fundamental cognitive abilities

Exposure to air pollution during pregnancy or during early life is linked to a reduction in cognitive abilities during child development. Greater fine particulate matter 2.5 exposure between fetal stage and 7 years old was associated with lower working memory scores in boys at age 10. Early life exposure to PM2.5 was also correlated with attention problems in both boys and girls.
