Laboratory of Brain Imaging
Head: Artur Marchewka
Our core facility is focused on providing high quality brain imaging using multiple magnetic resonance methods for research ranging from neuropsychology, through clinical studies, till pharmacological studies.
Currently, several non-invasive neuroimaging funded projects on various topics related to human cognition (e.g. attention, memory, reading, deception, stress, empathy) are underway.
3T MRI scanner Siemens TRIO equipped with:
• 32 channel head coil compatible with iPAT
• 12 channel head coil compatible with iPAT
• circular polarized transmit/receive coil for spectroscopy (Tx/Rx CP Head)
• hardware and software for presentation of visual and auditory stimuli
• fMRI compatible: EEG, EMG (electromyography), GSR (galvanic skin response)
• transcanial magnetic stimulator (TMS)
• Functional Magnetic Resonance Imaging (fMRI)
• Pattern Recognition and Multivariate methods for fMRI
• Voxel-Based Morphometry
• Resting-State fMRI
• Diffusion Tensor Imaging (DTI; up to 256 directions, b≤10 000s/mm2)
• proton magnetic resonance spectroscopy (single voxel and chemical shift imaging)
• perfusion (cerebral blood flow imaging)
Current research activities:
• effects of diet on structural and functional markers of human and animal brain
• processing of emotionally charged visual stimuli
• effects of emotion on long term memory
• anatomical markers of dyslexia in multi-site MRI study
