Making a memory positive or negative

Researchers have discovered the molecule in the brain responsible for associating good or bad feelings with a memory. Their discovery paves the way for a better understanding of why some people are more likely to retain negative emotions than positive …

No evidence that depression is caused by low serotonin levels, finds comprehensive review

After decades of study, there remains no clear evidence that serotonin levels or serotonin activity are responsible for depression, according to a major review of prior research.

Lymphatics help ‘seed’ early brain cells in zebrafish

A recent article demonstrated how lymphatics — which remove waste from the rest of the body — are also associated with microglia and brain development in zebrafish.

When did the genetic variations that make us human emerge?

The study of the genomes of our closest relatives, the Neanderthals and Denisovans, has opened up new research paths that can broaden our understanding of the evolutionary history of Homo sapiens. A new study has made an estimation of the time when som…

Vitamin B6 supplements could reduce anxiety and depression

Trial participants reported feeling less anxious or depressed after taking high doses of Vitamin B6 for a month. The trial provides evidence that the calming effect B6 has on the brain could make it effective in preventing or treating mood disorders.

Discovery advancing epilepsy research

A team of researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE).

Discovery of molecular signatures of immature neurons in human brain throughout life provide insights into brain plasticity

Researchers have used advanced techniques to show that, in a key memory region of the brain called the hippocampus, immature, plastic neurons are present in significant numbers throughout the human lifespan. The findings may resolve a long-running cont…

Brains of children with autism may not always ‘see’ body language, study finds

Researchers have found that children with autism spectrum disorder may not always process body movements effectively, especially if they are distracted by something else.

Scientists reveal new evidence of key mechanism in Alzheimer’s

Rutgers scientists have found more clear-cut evidence of how the destructive proteins linked to Alzheimer’s disease attack human brain cells and destroy surrounding tissue.

New insights into melanoma brain metastases

Cancer researchers have completed one of the most comprehensive studies of the cells inside melanoma brain metastases.
