Continued cocaine use disrupts communication between major brain networks

New research provides new insights into the brain processes underlying cocaine addiction. The findings are crucial for developing new therapeutics and identifying an imaging marker for cocaine use disorders.

Molecular clusters on glial cells show they are more than our brain’s ‘glue’

Researchers report that a single glial cell uses different molecules to communicate with different neurons. Careful clustering of these molecules ensures that the glial cell can conduct a distinct ‘conversation’ with each neuron. Through these molecula…

Neurons help flush waste out of brain during sleep

Researchershave found that brain cell activity during sleep is responsible for propelling fluid into, through and out of the brain, cleaning it of debris.

In fight against brain pathogens, the eyes have it

The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into t…

Could we assess autism in children with a simple eye reflex test?

Scientists may have discovered a new way to test for autism by measuring how children’s eyes move when they turn their heads.

More than just neurons: A new model for studying human brain inflammation

Scientists have created a novel organoid model of the human brain that contains astrocytes — which have been excluded from other models thus far — to study inflammation in diseases like Alzheimer’s. Using this model, they have already found a potenti…

Addressing societal concerns of genetic determinism of human behavior by linking environmental influences and genetic research

In a new perspective article, researchers underscore the importance of integrating environmental effects into genetic research. The authors discuss how failure to do so can perpetuate deterministic thinking in genetics, as historically observed in the …

New study links placental oxygen levels to fetal brain development

A new study shows oxygenation levels in the placenta, formed during the last three months of fetal development, are an important predictor of cortical growth (development of the outermost layer of the brain or cerebral cortex) and is likely a predictor…

Learning and memory problems in down syndrome linked to alterations in genome’s ‘dark matter’

The activity of Snhg11, a gene found in the ‘dark matter’ of the genome, is critical for the function and formation of neurons in the hippocampus, specifically in an area critical for learning and memory. Researchers have discovered the gene is less ac…
