Evidence for Brainstem Contributions to Autism Spectrum Disorders

Olga I Dadalko, Brittany G Travers
2018 Frontiers in Integrative Neuroscience  
In all, there is preliminary evidence for brainstem involvement in ASD, but a better understanding of the brainstem's role would likely pave the way for earlier diagnosis and treatment of ASD.  ...  Although there is a mounting body of knowledge of cortical and cerebellar contributions to ASD, our knowledge about the early developing brainstem in ASD is only beginning to accumulate.  ...  ACKNOWLEDGMENTS We would like to thank the Marsh Center for Exercise and Movement Research and the Hartwell Foundation for the generous support of this work.  ...

Mark T. Wallace, Ryan A. Stevenson
2014 Neuropsychologia  
In addition to their role in sensory processing, these deficits in multisensory temporal function may play an important role in the perceptual and cognitive weaknesses that characterize these clinical  ...  Within this context, focus on improving the acuity of multisensory temporal function may have important implications for the amelioration of the "higher-order" deficits that serve as the defining features  ...  Plotted is the gain in neuronal response (i.e., multisensory interactive gain) as a function of the stimulus onset asynchrony between the visual and auditory stimuli.  ...
