Human Brain Control of Locomotion (HBCL) lab
The HBCL lab is a large space (1,000 sq.ft.) equipped with a neuronavigated, non-invasive brain stimulator and split belt treadmill funded through the Canada Foundation for Innovation. It is located on the downtown McGill campus within less than 5 minutes walking distance from the McConnell Brain Imaging Centre (BIC) of the Montreal Neurological Institute.
Magstim Super Rapid-2
The Magstim Super Rapid-2 is used as a diagnostic tool with single pulses to induce motor evoked potentials (induces muscle twitches to be measured with the EMG module). This module is also used to deliver non-invasive brain stimulation of selected cortical brain regions. The unit can deliver repetitive pulses which can increase or decrease cortical excitability, depending on stimulus frequency.
The BiStim package allows us to stimulate two brain areas within very short time intervals. This type of stimulation taps on inhibitory drive between cerebral hemispheres. These measures can help us determine the effect each hemisphere has on one another.
Rapid-2 Air Cooled Coil package
The Air Cool Coil package ensures that stimulation protocols are not interrupted because of overheating coils. This is most useful when the Magstim Super Rapid-2 during repetitive pulses (especially when stimulating at higher frequency).
Magstim 200-2 Double 70mm Remote Control Coil
This coil is driven by floor pedals so that the experimenter’s hands are free to hold the coil in position on the subject’s head in the desired position.
D70 alpha coil
This coil is used with the BiStim-2 Package to deliver pulses to both brain hemispheres within very short periods of time (typically 2-10 ms).
EMG Interface Module
The electromyography (EMG) interface module measures muscle responses to stimulation (motor evoked potentials; MEP). Measures derived from the muscle responses are MEP amplitude and latency from the stimulus presentation.
The Brainsight 2 system is used to guide TMS on specific cortical landmarks of the brain, irrespective of intra-individual differences in anatomy. The system uses the subject’s anatomical MRI which is registered with the subject’s head with a high-precision motion capture system.
Split belt treadmill
With the split-belt treadmill, both feet can be moved at different velocities. The brain must adapt the walking pattern to walk on such treadmills. The treadmill is used to measure locomotor adaptation with PET imaging under controlled conditions.
The HBCL lab has several workstations for students and fellows equipped with computers.
The McConnell Brain Imaging Centre (BIC) of the Montreal Neurological Institute’s world-class facilities include some of the most advanced MR, PET, and MEG imaging devices available. For our research we most commonly use the human Magnetic Resonance Imaging (MRI) and human Positron Emission Tomography (PET) scanners. For more information, visit their website. For image analysis, we use several tools including the MINC tools of the BIC, SPM, FSL, SurfStat, CIVET, Vinci.
Center for Interdisciplinary Research in Rehabilitation (CRIR) – Jewish Rehabilitation Hospital (JRH )Site
The Jewish Rehabilitation Hospital research site of CRIR hosts several laboratories equipped with state-of-the-art technology. Visit the Hospital’s website for more information on facilities available to our students and fellows. Collaborative projects with other researchers from the CRIR-JRH site are encouraged.
