The direction of attentional bias in forty normal adults was assessed using a computer generated line bisection task. A 4 (viewing distance)x4 (line length)x2 (cursor starting position) repeated measures factorial design was employed. As predicted, differences in bisection performance as a function of viewing distance were observed. The findings confirmed(More)
Histaminergic neurons of the tuberomammillary nucleus (TMN) are hypothesized to promote wakefulness, but little is known about the activity of these cells during spontaneous behavior. We measured histaminergic neuron activity in the dorsomedial, ventrolateral, and caudal TMN at four different times using Fos and adenosine deaminase immunohistochemistry and(More)

A total of 3305 older adults with a mean age of(More)
Two single case studies are presented examining the effects of imagined limb activation in participants with unilateral visual neglect and severe physical disabilities. The first study employed a standard ABBABBA design where the participant was asked to imagine making movements with his left arm during the intervention conditions. Neglect was(More)
