Part 6/9:
Using Bing, he finds literature indicating that synesthesia is more common among neurodiverse individuals, including those with ASD. He learns that increased cross-activation or connectivity between different sensory regions in the brain could underlie both synesthesia and tinnitus. This aligns with existing research suggesting that enhanced neural cross-talk may produce sensory blending or perceptions like tinnitus in some individuals.
He cites a study on functional MRI (fMRI) findings which examine blood flow changes in the brain, shedding light on how neural activity correlates with tinnitus perception. Overall, the literature supports a model where atypical neural connectivity might account for these perceptual phenomena.
