The developing ventral visual pathway in a young patient following right posterior hemispherectomy

Visual saliency and spike timing in the ventral visual pathway.

Visual saliency is a fundamental yet hard to define property of objects or locations in the visual world. In a context where objects and their representations compete to dominate our perception, saliency can be thought of as the "juice" that makes objects win the race. It is often assumed that saliency is extracted and represented in an explicit saliency map, which serves to determine the locat...

Cavernous Sinus and Generalized Venous Thrombosis Following Rhinoplasty in a Young Patient

Venous thromboembolism at lower age groups and in the absence of other known risk factors should raise doubt of underlying genetic disorders and thombophilia. It is discovered unexpectedly in various medical procedures and may cause severe complications and life threatening problems. In the current study, potentially life threatening complications of a genetic disorder in a previously healthy...

Line bisection following hemispherectomy.

Two left- and right-hemispherectomized patients with contralateral hemianopia and 20 normal controls were administered a line bisection task. All hemispherectomized patients showed a strong bisection bias towards their blind visual field. This contralateral bias persisted when patients were forced to start scanning within their blind hemifield, supporting the idea of a strategic adaptation of a...

The Functional Organization of the Ventral Visual Pathway in Humans

How parallel is visual processing in the ventral pathway?

Visual object perception is usually studied by presenting one object at a time at the fovea. However, the world around us is composed of multiple objects. The way our visual system deals with this complexity has remained controversial in the literature. Some models claim that the ventral pathway, a set of visual cortical areas responsible for object recognition, can process only one or very few...
