Motor interactions between mouth, hand and foot

Abstract: Intensive contraction of a muscle modulates the corticospinal excitability (CSE) not only of the contracting muscle, but also of the resting muscles located in remote parts of the body; this is the so-called “remote effect”. We investigated to what extent the CSE of a hand muscle is modulated during preparation and execution of mouth and foot movements either separately or in combination. Hand-muscle CSE was estimated based on motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) and recorded from the first dorsal interosseous (FDI) muscle.

Short Bio: Naeem received his Ph.D. in Human Movement Science from the University of Verona and VU University of Amsterdam, where he aimed to tackle the interaction between sound perception and motor behavior, and sought to unravel its neural underpinnings. Thereafter, he spent time as a postdoc at the Cognitive Brain Research Unit of the University of Helsinki. Recently, he joined the laboratory of Prof. Isabelle Peretz as a postdoc to perform research in the field of neuroscience of music.
