La
plupart des personnes atteintes de troubles du spectre autistique
présentent une hypersensibilité / hyposensibilité à divers types de
stimuli sensoriels. Bien
que plusieurs hypothèses telles qu'une plus grande sensibilité aux
stimuli, des altérations de la structure et de la fonction cérébrales,
et un dysfonctionnement des systèmes inhibiteurs au niveau moléculaire
aient été suggérés, il n'existe aucune preuve convaincante. Nous
avons trouvé que les individus ayant une résolution temporelle élevée
avaient tendance à avoir une forte hypersensibilité aux stimuli
sensoriels et vice versa.

Abstract
Most individuals with autism-spectrum
disorders have hypersensitivity/hyposensitivity to various types of
sensory stimuli. Although several hypotheses such as higher sensitivity
to stimuli, alterations in brain structure and function, and dysfunction
of inhibitory systems at the molecular level have been suggested, there
is no convincing evidence. We found that individuals with high temporal
resolution tended to have strong hypersensitivity to sensory stimuli
and vice versa. In addition, we focused on a case with extraordinarily
high temporal resolution across the tactile, auditory, and audio-tactile
domains. We believe that studying such an extreme case of temporal
processing could facilitate an understanding of the neural basis of time
perception.
