Reduced Hand Specialization and Idiosyncratic Visuomotor Strategies in Autism During Naturalistic Object Manipulation

open access: yesAutism Research, EarlyView.
ABSTRACT Autistic individuals exhibit altered perceptual and visuomotor behaviors, potentially due to reduced cortical specialization. The current study focuses on handedness, a robust marker of cerebral specialization, which is less right‐biased in autism.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
