Brain imaging shows how nonverbal children with autism have slower response to sounds
Nonverbal children on the autism spectrum have a slower response to auditory stimulation. The longer response times were associated with poor communication skills. Brain imaging of the auditory cortex could serve as a biomarker for measuring the likelihood of language impairment in those with ASD.... Read More...

The scientific case for brain simulations
Researchers report a need for open, general purpose simulation engines that can run different models of the brain at different levels of biological detail.... Read More...
Detecting dementia’s damaging effects before it’s too late
Using MEG neuroimaging, researchers identify abnormalities in functional activity in brain regions which look structurally normal on conventional MRI scans. The findings could help with early detection of primary progressive aphasia.... Read More...
Room for thought: Brain region that watches for walls identified
MEG neuroimaging implicates the occipital place area (OPA) in our ability to rapidly sense our surroundings. The findings may advance improving machine learning and robotics technology aimed at mimicking visual processes in the human brain.... Read More...
VA-led study of combat personnel with brain injuries pinpoints abnormal brain waves
Neuroimaging study reveals veterans who suffered a mild traumatic brain injury (mTBI) have higher levels of fast, high-frequency gamma waves in the prefrontal and posterior parietal lobes, areas of the brain associated with consciousness, attention and problem-solving.... Read More...
