Look and see: How the brain moves your eyes about

Look and see: how the brain moves your eyes about.

Two major cortical streams are involved in the generation of visually guided saccadic eye movements: the anterior and the posterior. The anterior stream from the frontal and medial eye fields has direct access to brainstem oculomotor centers. The posterior stream from the occipital cortices reaches brainstem oculomotor centers through the superior colliculus. The parietal cortex interconnects w...

See your brands through your customers' eyes.

Subaru markets an L.L. Bean Outback station wagon. Dell stamps Microsoft and Intel logos on its computers. Such inter-weaving of different companies' brands is now commonplace. But one of the central tools of brand management-portfolio mapping--has not kept pace with changes in the marketplace. Most conventional brand maps include only those brands owned by a company, arranged along organizatio...

How your hand drives my eyes.

When viewing object-related hand actions people make proactive eye movements of the same kind as those made when performing such actions. Why is this so? It has been suggested that proactive gaze when viewing a given hand action depends on the recruitment of motor areas such as the ventral premotor (PMv) cortex that would be involved in the execution of that action. However, direct evidence for...

When your eyes see more than you do

Visual information is used by the brain to construct a conscious experience of the visual world and to guide motor actions [1]. Here we report a study of how eye movements and perception relate to each other. We compared the ability of human observers to perceive image motion with the reliability of their eyes to track the motion of a target [2], [3] and [4], the goal being to test whether both...
