Dear colleagues This week we will discuss the design of a set of MEG and fMRI experiments that could be used to form the basis of a 'gold-standard' dataset that could be used to compare and contrast current MEG analysis techniques as well allow the testing of future analysis algorithms. Andy Young has proposed that we start this exercise by collecting data that would primarily activate sensory cortices as one should be able to predict the outcome. The aim would be to collect data in as 'perfect' a manner as possible and would include the recording of eye movements, EOG and ECG signals. The specific design of the experiments will be discussed this Thursday at 4pm. We will also discuss how we will use a suite of analysis tools to examine different source localisation and reconstruction methods. Examples of how this could be achieved will be presented by members of the YNiC team but the idea is that an analysis task-force would be encouraged to tackle the data. One of the aims is to use this data to refine our data analysis and statistical methods. We hope this will lead to clear guidelines as to the 'best' way to approach MEG experimentation and source analysis. The outcomes will determine how we develop the analysis software framework and will, hopefully, result in even clearer documentation for users as well as publications. Do come and contribute.
