Sensory processing in the context of "Erogenous zone"

The neurodiversity paradigm is a framework for understanding human brain function that considers the diversity within sensory processing, motor abilities, social comfort, cognition, and focus as neurobiological differences. This diversity falls on a spectrum of neurocognitive differences. The neurodiversity movement views autism as a natural part of human neurological diversity—not a disease or a disorder, just "a difference".

Neurodivergences include autism, attention deficit hyperactivity disorder (ADHD), bipolar disorder (BD), developmental prosopagnosia, developmental speech disorders, dyslexia, dysgraphia, dyspraxia, dyscalculia, dysnomia, intellectual disability, obsessive–compulsive disorder, schizophrenia, sensory processing disorder (SPD), synesthesia, and Tourette syndrome.

A cortical homunculus (from Latin homunculus 'little man, miniature human') is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body. Nerve fibres—conducting somatosensory information from all over the body—terminate in various areas of the parietal lobe in the cerebral cortex, forming a representational map of the body.

Findings from the 2010s and early 2020s began to call for a revision of the traditional "homunculus" model and a new interpretation of the internal body map (likely less simplistic and graphic), and research is ongoing in this field.
