I have uploaded a number of eye movement recordings taken from various projects I have been involved with over the years using the Eyelink eye tracking system, to a dedicated U-tube channel! Anyone can browse, ask questions or comment on the videos and I have given links to the relevant publications where available. I’ll be uploading some more soon but take a look here:

The School of Psychology has recently just taken delivery of the next generation of Eyelink system the Eyelink 1000 http://www.sr-research.com/index.html

Most of the videos on the U-tube site were taken with the Eyelink 2. The Eyelink 1000 allows for “heads free” tracking at high spatial and temporal resolution. We plan to use it for testing in neurological patients as well as at the forthcoming Summer Scientist research day http://summerscientist.blogs.lincoln.ac.uk/

This week I will be visiting the Regional Eating Disorders Service at Ulleval Hospital University of Oslo:

Clinical psychologist and current PhD student Ian Frampton has been carrying out research based at the unit using fMRI to determine if individuals with anorexia nervosa have abnormal patterns of activity in the insula cortex of the brain. He is examining patterns of activity in patients and controls while they perform cognitive tasks that tax working memory, executive control and attention, some of which are specially modified to use materials which might activate body image or food reward processing systems.

Historically, the insula cortex was known to play an important role in advanced processing neural signals coming from the gut (some people have even called it the “hippocampus of the gut”), but more recently it is perhaps more widely known for its involvement in emotion and socio-economic decision making  (see earlier post  on our coordination game fMRI study).  Ians research spans  the two fields, so I am really pleased to be involved with it and very much looking forward seeing his latest imaging results!

The research has the promise to provide better techniques for assessing and diagnosing eating disorders, as well as better fundamental understanding of the neural, cognitive and emotional mechanisms involved in anorexia and related conditions.
