The MRI facility features a 3T Philips Ingenia scanner equipped with a 32-channel head coil, tailored for comprehensive neuroimaging studies. Its capabilities encompass anatomical imaging, functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI), and magnetic resonance spectroscopy. Within this lab, a sophisticated visual stimulation system is available, capable of rendering 3D and virtual reality experiences, while an auditory stimulation system, enhanced by active noise cancelling, enriches auditory investigations. Furthermore, it incorporates an eyetracker for gaze and pupil size tracking, optical motion capture cameras for precise movement analysis, and additional physiological recordings to monitor heart rate and respiration. Moreover, an MRI-compatible stepping robot facilitates the assessment of gait-like behavior within the MRI environment. The MRI lab leverages these advanced tools for in-depth explorations of sensory perception, motor learning, and cognitive functions, employing cutting-edge data analytics, including deep learning models, to uncover neural correlates underlying these processes.
Key Technologies
The visual system with an integrated eyetracker (VisualSystem HD, NordicNeuroLab) enables the presentation of high-quality graphics and videos, including 3D content and virtual reality environments. This innovation unlocks exciting possibilities in functional magnetic resonance imaging (fMRI) research, as it immerses participants or patients in new environments, facilitating the examination of brain activity patterns during complex behaviors. Additionally, it offers real-time monitoring of participants’ gaze direction and pupil dynamics.
Utilizing MRI-compatible optical motion capture cameras (Qualysis) enables the precise tracking of reflective markers affixed to participants’ hands or fingers. This technology facilitates concurrent movement analysis and brain activity recording. As a result, researchers can investigate the neural mechanisms involved in the control of hand and finger movements, both in healthy individuals and those with pathological conditions.
Ultra-slim MRI-compatible active noise-canceling headphones (Optoactive II, Optoacoustics) effectively mitigate MRI scanner noise through both active and passive noise reduction methods. These headphones offer a high-quality, clear audio experience for the delivery of auditory stimuli, music, and communication. Their use facilitates the exploration of the rewarding aspects of music and its potential applications in enhancing the efficacy of neurorehabilitation therapy.
