WE'RE RECRUITING!

Participants Needed for fNIRS Hand and Foot Movement Study

We are looking for volunteers aged 18-35 years to take part in a study of hand and foot movement. Your participation would involve three sessions, and the sessions will be about 2.5-3 hours long each, for a total of ~7.5-9 hours of participation. You must a) be between the ages of 18-35 years old, b) have no musculoskeletal upper and lower limb impairments, c) possess normal or corrected-to-normal vision, d) no self-reported colour deficiency (including colourblindness), e) have no self-reported learning impairments that would prevent you from understanding the purpose of the study f) be right handed and right footed g) be free of any neurological impairment that would impact your ability to produce a motor response h) must be fluent in English i) must not be allergic to latex or rubbing alcohol. In appreciation for your time, you will receive payment at a rate of $10 per hour. The purpose of this study is to investigate the magnitude and reliability of certain brain responses. These responses are measured using functional near-infrared spectroscopy. Functional near-infrared spectroscopy requires the removal of all head garments. This research is important to form new methodologies for future research, including those involving spinal cord injury. 

 

Student investigators for this study include: Patrick Dans (BSc), Claudia Turco (BSc), Stevie Foglia (MSc), Stephen Toepp (MSc), and Tarra D’Hoine.

Participants Needed for TMS Sensory Control Study
 

We are looking for right-handed, volunteers aged 18-35 years to take part in a research study of the sensory control of the hand. Your participation would involve three sessions, and the sessions will be about 4-5 hours long. In appreciation for your time, you will receive payment at a rate of $10 per hour. The purpose of this study is to investigate if cutaneous input is important for modulating motor cortex function, and if this process is governed by a phenomenon known as "afferent inhibition". Afferent inhibition is evoked by delivering nerve stimulation to the wrist and a pulse of TMS to the motor area of the brain. This research will provide valuable information that will be fundamental for understanding the mechanisms of sensorimotor behaviour. This study has been reviewed by the Hamilton Integrated Research Ethics Board (HiREB) under project #7782.

Participants Needed for TMS Pharmacology Study

We are looking for right-handed, male volunteers aged 21-35 years to take part in a study of the sensory control of the hand. You will be asked to receive TMS pulses to the motor areas of the brain and peripheral nerve stimulation to the hand. You will also be administered the pharmacological agent L-DOPA.


Your participation would involve two sessions, and the sessions will be about 4.5 hours long. In appreciation for your time, you will receive payment at a rate of $20 per hour. The purpose of this study is to investigate the mechanisms that underlie the "afferent inhibition" neural circuit in the brain. Afferent inhibition is evoked by delivering nerve stimulation to the wrist and a pulse of TMS to the motor area of the brain. This study involves the administration of L-DOPA, a common medication used to treat Parkinson's disease. This will allow us to test the effects of dopamine on the functioning of these neural circuits.

Participants Needed for Muscle Fatigue Study
 

This study is recruiting males and females between the age of 18 and 30 to participate in four 2-hour laboratory sessions. The purpose of this investigation is to examine how changes in brain excitability are related to changes in muscle activation during muscle fatigue. In addition, this study explores the relationship between map changes (cortical and muscle) and resistance to fatigue. Researchers have shown that certain regions of the brain become less excitable after fatigue and that different parts of a muscle become more active as fatigue progresses. Changes in the activity of different muscle areas are also related to the ability of a muscle to resist fatigue. This research will help scientists to understand how changes in brain excitability that are related to disease, injury or physiological perturbation interact with changes in muscle activity and function (i.e. resistance to fatigue).
