Neurotypical brains engage in sensory adaptation and habituation: the longer they are in the presence of a sound, smell, texture, or visual cue, the more their brain learns to ignore it, and allow it to fade into the background. Their neurons become less likely to be activated by a cue the longer they are around it. The exact opposite is true for Autistic people: the longer we are around a stimulus, the more it bothers us.[2]
