Accommodative response and cortical activity during sustained attention
Greater accommodative lag and vergence deficits have been linked to attentional deficits similar to those observed in Attention Deficit Hyperactivity Disorder (ADHD). The purpose of the present study was to assess the effect of accommodative-vergence stress on a measure of sustained attention (Conners CPT) used in the diagnosis of ADHD. Twenty-seven normal non-ADHD adults completed the Conners ...
متن کاملIncreases in cortical acetylcholine release during sustained attention performance in rats.
Acetylcholine (ACh) efflux in the frontoparietal cortex was studied with in vivo microdialysis while rats performed in an operant task designed to assess sustained attention. Transferring animals from the baseline environment into the operant chambers elicited a robust increase in cortical ACh efflux that persisted throughout the 18-min pre-task period. Subsequent performance in the 36-min sust...
متن کاملThe roles of cortical oscillations in sustained attention.
We rely on sustained attention to protect task performance against fatigue and distraction. Time-related variations in attention correlate with amplitude changes of specific cortical oscillations. However, the ways in which these oscillations might support sustained attention, how these oscillations are controlled, and the extent to which they influence one another remain unclear. We address th...
متن کاملDelayed Striate Cortical Activation during Spatial Attention
Recordings of event-related potentials (ERPs) and event-related magnetic fields (ERMFs) were combined with functional magnetic resonance imaging (fMRI) to study visual cortical activity in humans during spatial attention. While subjects attended selectively to stimulus arrays in one visual field, fMRI revealed stimulus-related activations in the contralateral primary visual cortex and in multip...
متن کاملFactors associated with sustained attention during an activity intervention in persons with dementia.
BACKGROUND/AIMS Are the noncognitive factors of self-reported mood and personality related to sustained attention in nursing home residents with dementia during an activity intervention? METHODS Intervention data from a randomized clinical trial were used to address the aim of this project. Subjects were 128 nursing home residents who were assessed for mood, personality, behavioral indicators...
