>>Hyper-Connected Autistic Brain<<
There are too many sensory receptors in the Autistic brain.
The overload of incoming sensory stimuli constantly overwhelming the brain's ability to process, creates high levels of anxiety.
The presence of other people adds complex sensory stimuli, including nonverbal social cues, taxing the nervous system even further.
Solitude and repetitive routines help keep unscripted surprises (and resulting sensory events) to a minimum, thus keeping the overload at more manageable levels.
