[HTML][HTML] Beta oscillations reflect changes in motor cortex inhibition in healthy ageing

HE Rossiter, EM Davis, EV Clark, MH Boudrias… - Neuroimage, 2014 - Elsevier
Beta oscillations are involved in movement and have previously been linked to levels of the
inhibitory neurotransmitter GABA. We examined changes in beta oscillations during rest and …

[HTML][HTML] Predicting behavioural response to TDCS in chronic motor stroke

J O'Shea, MH Boudrias, CJ Stagg, V Bachtiar… - Neuroimage, 2014 - Elsevier
Transcranial direct current stimulation (TDCS) of primary motor cortex (M1) can transiently
improve paretic hand function in chronic stroke. However, responses are variable so there is …

Assessing the integrity of corticospinal pathways from primary and secondary cortical motor areas after stroke

R Schulz, CH Park, MH Boudrias, C Gerloff… - Stroke, 2012 - Am Heart Assoc
Background and Purpose— Aside from the primary motor cortex, the corticospinal tract (CST)
also receives fibers from dorsal and ventral premotor cortices and supplementary motor …

Theta burst stimulation in the rehabilitation of the upper limb: a semirandomized, placebo-controlled trial in chronic stroke patients

…, C Gillini, G Musumeci, MH Boudrias… - … and neural repair, 2012 - journals.sagepub.com
Background. Noninvasive cortical stimulation could represent an add-on treatment to enhance
motor recovery after stroke. However, its clinical value, including anticipated size and …

Do movement-related beta oscillations change after stroke?

HE Rossiter, MH Boudrias… - Journal of …, 2014 - journals.physiology.org
Stroke is the most common cause of physical disability in the world today. While the key
element of rehabilitative therapy is training, there is currently much interest in approaches that “…

Acute cardiovascular exercise promotes functional changes in cortico-motor networks during the early stages of motor memory consolidation

F Dal Maso, B Desormeau, MH Boudrias, M Roig - Neuroimage, 2018 - Elsevier
A single bout of cardiovascular exercise performed immediately after practicing a visuo-motor
tracking task has been shown to improve the long-term retention of this motor skill through …

[HTML][HTML] Assessing a standardised approach to measuring corticospinal integrity after stroke with DTI

C Park, N Kou, MH Boudrias, ED Playford, NS Ward - NeuroImage: clinical, 2013 - Elsevier
The structural integrity of the corticospinal tract (CST) after stroke is closely linked to the
degree of motor impairment. Simple and reliable methods of assessing white matter integrity …

[HTML][HTML] Changes in the location of cortico-muscular coherence following stroke

HE Rossiter, C Eaves, E Davis, MH Boudrias, C Park… - NeuroImage: Clinical, 2013 - Elsevier
Stroke results in reorganization of residual brain networks. The functional role of brain regions
within these networks remains unclear, particularly those in the contralesional hemisphere…

Output properties and organization of the forelimb representation of motor areas on the lateral aspect of the hemisphere in rhesus macaques

MH Boudrias, RL McPherson, SB Frost… - Cerebral …, 2010 - academic.oup.com
Motor output capabilities of the forelimb representation of dorsal motor area (PMd) and
ventral motor area (PMv) were compared with primary motor cortex (M1) in terms of latency, …

[HTML][HTML] Disrupted functional network integrity and flexibility after stroke: relation to motor impairments

S Larivière, NS Ward, MH Boudrias - NeuroImage: Clinical, 2018 - Elsevier
Previous studies investigating brain activation present during upper limb movement after
stroke have greatly detailed activity alterations in the ipsi- and contralesional primary motor …
