We have developed some Matlab tools for [http://www.mrc-cbu.cam.ac.uk/research/eeg/matlab_tools.html basic data processing] and [http://www.mrc-cbu.cam.ac.uk/research/eeg/matlab_tools_mn.html source analysis] of EEG data.
Welcome to the CBU EEG lab
The CBU EEG lab hosts a variety of research projects in the areas of perception, language and cognition. We employ a 128-channel, active electrode [http://www.brainproducts.com/productdetails.php?id=2 BrainAmp] ([http://www.brainproducts.com/ Brain Products]) EEG setup and all recordings are performed in an acoustically and electrically shielded chamber. The lab is equipped with a Polhemus Digitisation System, as well as with E-Prime and Cogent stimulation systems. For data processing, we have available the software packages SPM, Curry, MNE, BESA, ASA, Scan, Brain Vision Analyzer, etc ([http://imaging.mrc-cbu.cam.ac.uk/meg/AnalyzingData see here]). We also develop our own analysis tools in Matlab.
In addition to measuring ERPs, we perform MEG (magnetoencephalography) in our [http://imaging.mrc-cbu.cam.ac.uk/meg CBU MEG Laboratory]. We also conduct fMRI experiments using the [http://imaging.mrc-cbu.cam.ac.uk/mri CBU Siemens Tim Trio 3T system] and Wolfson Brain Imaging Centre in Cambridge.
We use methods with high temporal resolution such as magnetoencephalography (MEG) and electroencephalography (EEG) to reveal the precise time-course of cognitive processes such as language, auditory/visual perception and decision making. In the case of language comprehension, for example, time course information is crucial, because language comprehension is a dynamic process that involves the integration of various types of information (phonological, syntactic, semantic etc) over a very short time interval. One of our primary goals is to integrate the precise temporal information provided by EEG and MEG with data obtained from functional Magnetic Resonance Tomography (fMRI).
