Atypical Pupillary Light Reflex in Individuals With Autism
We investigated pupillary light reflex (PLR) in 152 children with ASD, 116 typically developing (TD) children, and 36 children with non-ASD neurodevelopmental disorders (NDDs). Heart rate variability (HRV) was measured simultaneously to study potential impairments in the autonomic nervous system (ANS) associated with ASD. The results showed that the ASD group had significantly longer PLR latenc...
متن کاملUnreliable Evoked Responses in Autism
Autism has been described as a disorder of general neural processing, but the particular processing characteristics that might be abnormal in autism have mostly remained obscure. Here, we present evidence of one such characteristic: poor evoked response reliability. We compared cortical response amplitude and reliability (consistency across trials) in visual, auditory, and somatosensory cortice...
متن کاملMethod for Characterizing and Identifying Task Evoked Pupillary Responses During Varying Workload Levels
Understanding when operators are experiencing high workload is important in the design and implementation of Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) systems. Fortunately physiological metrics, such as pupillary reflexes, have been shown to correlate with increases in mental workload. This paper proposes an automated method for character...
متن کاملAtypical Gaze Behavior in Children with High Functioning Autism During an Active Balance Task
Background. Unusual gaze behavior in children with autism spectrum disorder (ASD) was reported very early in the literature. Objectives. The current study examined gaze behavior in children with ASD and typically developing (TD) children while performing an active balance task on the Wii balance board. Methods: 8 children (male) diagnosed with high-functioning ASD and 9 TD children (3 female, ...
متن کاملPupillary correlates of light-evoked melanopsin activity in humans
We investigated whether cones are the only photosensitive process mediating the photopic pupillary light reflex. New analyses were performed on previously published recordings, focusing on those evoked by the onset of photopically equated short- and long-wavelength stimuli. Comparisons between responses revealed contraction differences that slowly grew to a peak and gradually declined. The late...
