Atypical Cerebellar Responses are Associated with Altered Neural Habituation during Sensory Stimulation in Autism. [PDF]

Autism Res
ABSTRACT Sensory processing atypicalities are highly prevalent in autistic youth; yet, the neural mechanisms underlying these differences are not well understood. While the cerebellum plays a key role in sensorimotor coordination and is structurally and functionally atypical in the autistic brain, it has been overlooked in research investigating ...
