Clinical and Systems Neuroscience
Aston Brain Centre
I have used MEG to study cortical processing for over 10 years, initially looking at recognition memory during my PhD and now focusing on the neural correlates of pain processing.
In addition to a number of pain-related projects that I am currently running, as the Aston Brain Centre (ABC) MEG Research Fellow, I am responsible for creating and implementing an MEG Approved User Training programme. This programme will be established upon the completion of the new Aston Brain Centre in the summer of 2011.
