Bilateral deficits of transient visual attention in right parietal patients

Bilateral deficits of transient visual attention in right parietal patients.

Vision tells us not only what and where objects are but also when they appear and disappear. We have found that patients with right parietal damage have an unusual loss in the ability to differentiate object onset from offset. Specifically, when a single target flickers at the same frequency as five distractors, but out of phase (it is light when they are dark and vice versa), right parietal pa...

Deficits in visual cognition and attention following bilateral anterior cingulotomy.

A series of eight tests of visual cognitive abilities was used to examine pre- to post-operative performance changes in a patient receiving bilateral anterior cingulotomy. Compared with a set of eight matched control participants, post-operatively, the patient exhibited deficits in (a) the ability to sequence novel cognitive operations required to generate multipart images or rotate perceptual ...

Effectiveness of Attention Rehabilitation on Decreasing Selective Attention Deficits in Patients with Multiple Sclerosis

Objective: Multiple sclerosis (MS) is a progressive disease of CNS and cognitive impairment is a common concomitant of it that affects various aspects of cognitive functioning like attention and memory as well as attentional complex tasks such as selective attention. The present study investigated the effectiveness of attention rehabilitation on decreasing selective attention deficits in patien...
