Attention, perception and action

We are able to perceive and interact with the environment around us primarily because a filter of attention selects just the objects or feat..

2010 - 2015
Completed
Project icon

Thalamo-cortical organisation in visual information processing

This study will: (1) Increase our basic understanding of visual function that can help to explain many clinical perceptual disturbances. (2)..

2009 - 2011
Completed
Project icon

Afferent channels in vision

There are three distinct groups of cells that carry the visual information from the eyes to the brain, each pathway signaling a different as..

2008 - 2011
