Using gene editing, neuroscientists develop a new model for autism

Using CRISPR gene editing, researchers introduce the SHANK3 gene variant into macaque monkeys. SHANK3 has previously been linked to autism in humans. The monkeys with the SHANK3 mutations exhibited behavioral traits and brain activity patterns similar to those seen in humans on the autism spectrum, Researchers hope the new model will facilitate new avenues of research for ASD....

Brain activation provides individual-level prediction of bipolar disorder risk

Combining neuroimaging data with machine learning, researchers have identified patterns of brain activation during reward anticipation, associated with an increased risk of developing bipolar disorder. The patterns of neural activation predict the severity of mania symptoms in young adults who have not yet developed the disorder.... Read More...

Six fingers per hand: Polydactyly equals extra motor ability

Polydactyly, a condition where one is born with an extra finger, has significant benefits when it comes to motor skill and control. fMRI neuroimaging reveals those with extra fingers are able to move the digits independently of other fingers. The findings could help with the development of new prosthetics that extend motor abilities.... Read More...
