Dear All,

I'm pleased to announced that we're about to start a new study which will look at the relationship between the size of the hippocampus and performance on a topographical memory task.

The aim is to make use of MRI data collected in connection with previous and ongoing studies. We are looking to make contact with potential participants (healthy adults, aged 18-50) who have already had an MRI scan at YNiC or who will have one over the next 6-9 months. An additional constraint is that they should be available to take part in a brief (15-20 minute) psychological test later in the year.

If you have already or are about to conduct a study with suitable participants and are willing to help, we would like to hear from you so that we can begin the process of contacting subjects and identifying studies in which they have participated. We aim to make this as easy for you and the potential participants as possible. There is a also a panel of volunteers who have agreed to be approached regarding future studies at YNiC, and we intend to approach these via the Director. To respond, please use the link below (please be careful not to "reply to all"!):

You may yourself have had a scan and be interested in participating - if so, please contact us, and we can then begin the process of tracking down your scan and obtaining permission to analyze the data. There is no need to make a firm commitment at this stage, and as with all such studies, you would be free to withdraw at any time. If this fits you, please use the following link to reply to this message:
