Abnormal brain connections seen in preschoolers with autism

Preschoolers with autism spectrum disorder, or ASD, have abnormal connections between certain networks of their brains that can be seen using a special MRI technique, according to a new study. Researchers said the findings may one day help guide treatm…

Antibody removes Alzheimer’s plaques, in mice

Plaques of a brain protein called amyloid beta are a characteristic sign of Alzheimer’s disease. But nestled within the plaques are small amounts of another Alzheimer’s protein: APOE. Now, researchers have shown that an antibody not only targets APOE f…

Younger aged children with symptoms of ADHD have reduced brain size

Children as young as four years old with symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) showed reduced brain volumes in regions essential for behavioral control, according to a new study. The research represents the first comprehensive exa…

Looking deeper into brain function

As neuroscience enters the era of big data bases, a new approach could offer a deeper and more systematic understanding of brain function, scientists argue.

Prenatal stress changes brain connectivity in-utero

The time babies spend in the womb is far from idle. The brain is changing more rapidly during this time than at any other time in development. It is an active time for the fetus to grow and explore, and of course connect to its mother. New evidence fro…

Neural fingerprints of altruism

For at least 150 years, we know that traumatic brain injury can change several domains of behavior, impairing social behavior or memory, for instance, depending on which brain areas have been damaged. However, mapping the relation between brain areas a…

Ultrathin endoscope captures neurons firing deep in the brain

Researchers have developed an endoscope as thin as a human hair that can image the activity of neurons in the brains of living mice, giving researchers access to areas that cannot be seen with microscopes or other types of endoscopes.

Could these food supplements help treat psychosis?

A systematic review of eight trials of nutrient-based treatments in young people with first-episode psychosis suggests that some may improve symptoms.

Captured on film for the first time: Microglia nibbling on brain synapses

For the first time, researchers have captured microglia nibbling on brain synapses. Their findings show that the special glial cells help synapses grow and rearrange, demonstrating the essential role of microglia in brain development.

Brain development disorders in children linked to common environmental toxin exposures

Exposures of pregnant women and children to common thyroid-hormone-disrupting toxins may be linked to the increased incidence of brain development disorders, according to new research. The review describes how numerous, common chemicals can interfere w…
