In a recent neuroimaging study the comparison of intact vs. disturbed perception of global gestalt indicated a significant role of the temporo-parietal junction (TPJ) in the intact perception of global gestalt (Huberle and Karnath, 2012). This location corresponded well with the areas known to be damaged or impaired in patients with simultanagnosia after stroke or due to neurodegenerative disea...

There have been a number of reports of preserved face imagery in prosopagnosia. We put this issue to experimental test by comparing the performance of MJH, a 34-year-old prosopagnosic since the age of 5, to controls on tasks where the participants had to judge faces of current celebrities, either in terms of overall similarity (Of Bette Midler, Hillary Clinton, and Diane Sawyer, whose face look...

On January 14th we were deeply saddened to hear about the sudden death of Professor Glyn Humphreys. With this departure, the field of cognitive neuropsychology lost not only one of its most prominent and productive researchers, but also one of the most influential and beloved scientific mentors. Glyn Humphreys was born on 28 December 1954 in Ormskirk, Lancashire. He obtained a Bachelor's degree...

Jason Cuomo, MA Murray Flaster, MD José Biller, MD We provide a narrative account of 2 patients’ experiences with Bálint syndrome, a rare and debilitating neurologic disorder characterized by optic ataxia, ocular apraxia, and simultanagnosia. It was a quiet Thursday afternoon when A.S., a 68-year-old woman from a suburb of Chicago, awakened from a nap to the realization that something was terri...

In motion-induced blindness (MIB), salient objects in full view can repeatedly fluctuate into and out of conscious awareness when superimposed onto certain global moving patterns. Here we suggest a new account of this striking phenomenon: Rather than being a failure of visual processing, MIB may be a functional product of the visual system’s attempt to separate distal stimuli from artifacts of ...

Stroke patients with optic ataxia have an outstanding inability to perform spatially accurate movements to visual targets located in their peripheral visual field. Neuropsychological investigations of such patients contributed essentially to the two visual stream hypothesis which presumes dissociated actionand perception-related processing of visual information in the human brain. Here we revie...
