The Magnetoencephalography Lab (MEG Lab) is operational at CIMEC since 2009 and provides cutting edge scientific and technical support to people who wants to use MEG for their own research.
The main facility at the MEG lab is a Vectorview 306 channel magnetoencephalograph (ElektaNeuromag, Helsinki) which records biomagnetic activity from the brain every millisecond (maximum sampling rate 5 kHz) with an overall sensitivity of 2.3 fT by means of 102 magnetometers and 204 planar axial gradiometers. The lab is also endowed with state-of-the-art MEG compatible peripheral devices (visual, auditory, tactile and electrical stimulation) and for monitoring EEG activity and eye gaze positions concurrently to the MEG recordings. In addition, the lab offers computational resources for the use of MEG customized data analysis software. Co-registration with MRI anatomical imaging is possible and made easy by means of the nearby MRI Lab scanner. This strongly improves the precision in localization of magnetic field sources in the participant brain.
Quality and reliability of the recorded MEG signal (and peripherally recorded data) is crucial for MEG research; furthermore, experimental and analysis techniques are under fast development in the international MEG community. Thus a mission of the MEG Lab is:
- keep the lab recording and analysis standards up-to-date, managing and implementing required technological and methodological updates;
- provide customized support in experimental design, data acquisition and analysis.
The MEG lab team is also pursuing research on on how functional information flows between distant brain areas may orchestrate cognition, with a particular focus on spatial and non-spatial attention in the visual and auditory domain. Other ongoing projects include functional connectivity and non-linear dynamics in resting state awake and sleep activity, as well as neuro-feedback and real time MEG at the source level.
The lab team is active in promoting the use of MEG and relevant best practices, as a keytool in neuroscience.
