Hi Guest. I just wanted to let you know that there will be some service disruptions here over the next few days. We're moving to a new server and then the latest version of xenforo is going to be installed. ~ cheryl

    Misdirected neurons may underlie autism symptoms - SFARI

    Many people with autism are known to be overly sensitive to sensory stimuli, such as sound or light. However, the reasons for this, as well as for other symptoms of autism, remain poorly understood.

    Autism probably results from ‘abnormal’ junctions, or synapses, that connect neurons. This hypothesis is based largely on the many genes known to function at the synapse — such as SHANK3, NLGN1 and FMR1 — that have been found to be mutated in individuals with autism. It is also based on imaging studies that have reported altered functional connections between brain regions in people with autism.
