IAS Fellows' Seminar - High-resolution in vivo imaging of the human retina: A window of opportunity for visual neuroscience

13th February 2017, 13:00 to 14:00, IAS Seminar Room, Palace Green, Professor Hannah Smithson (Oxford University, UK)

Our research focuses on the neural mechanisms that underlie perception. Using a newly developed Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO), which measures and corrects optical distortions in the eye to obtain high-resolution images, we are able to resolve individual cells in the living human eye as it moves during a visual task. The AOSLO allows us to (i) monitor the structural and functional progression of retinal diseases at the cellular level; (ii) assess the fine control of eye-movements, with application as biomarkers for neurodegenerative conditions; and (iii) measure blood flow through the finest retinal capillaries in response to neural processing of visual stimuli at specific retinal locations. We are particularly interested in using such techniques to gain a deeper understanding of sensitivity control in the retina. Visualization of individual cells in the living human eye has the potential to revolutionize our understanding of vision, both in health and in disease.

Fellows' seminars take place on Monday lunchtimes in the seminar room at Cosin's Hall.

Places are limited and so any academic colleagues interested in attending a seminar should contact the Institute in advance to reserve a place.

The aim of these seminars is to develop new thinking on the big issues that are of current concern/interest for the Fellows . Each Fellow is asked to present a core idea that informs their current work, or a problem that they are tackling, that could benefit from cross-disciplinary thinking. These seminars are informal and designed to encourage discussion.
