Do instructions influence response to the Chinese version of the Movement-Specific Reinvestment Scale in community-dwelling older adults?
Both the MSRS-C (general) and MSRS-C (walking) with a six-point or a four-point response format showed good discrimination of older fallers from non-fallers. Older adults might respond to the MSRS-C with respect to the most challenging movements (e.g. fall-related movements) in their daily living. Geriatr Gerontol Int 2015; ●●: ●●-●●.
These findings provide evidence that dopamine transporters modulate neural activity in the DMN and anterior cingulate gyrus during visuospatial attention. Our findings suggest that dopamine modulates attention in part by regulating neuronal activity in posterior parietal cortex including precuneus (region involved in alertness) and cingulate gyrus (region deactivated in proportion to emotional interference). These findings suggest that the beneficial effects of stimulant medications (increase dopamine by blocking DAT) in inattention reflect in part their ability to facilitate the deactivation of the DMN.
