Amputees can move their phantom limb at will. These 'movements without movements' have generally been considered as motor imagery rather than execution, but amputees in fact perform both executed and imagined movements with they report distinct perceptions during each task. Behavioural evidence for this dual ability comes from the that are associated stump muscle contractions whereas not, slower intact hand speed of is identical hands. Since neither execution nor imagination produces any...
Training and immobilization are powerful drivers of use-dependent plasticity in human primary motor hand area (M1HAND). In young right-handed volunteers, corticomotor representations the left first dorsal interosseus abductor digiti minimi muscles were mapped with neuronavigated transcranial magnetic stimulation (TMS) to elucidate how finger-specific training interact within M1HAND. A group volunteers trained track a moving target on smartphone index or little finger for one week. Linear...
The modular organization of the cortex refers to subsets highly interconnected nodes, sharing specific cytoarchitectural and dynamical properties. These properties condition level excitability local pools neurons. In this study, we described TMS evoked potentials (TEP) input-output provide new insights into regional cortical excitability. We combined robotized with EEG disentangle region-specific TEP from threshold saturation describe their oscillatory contents. Twenty-two young healthy...
Stroke as the leading cause of adult long-term disability and has a significant impact on patients, society socio-economics. Non-invasive brain stimulation (NIBS) approaches such transcranial magnetic (TMS) or electrical (tES) are considered potential therapeutic options to enhance functional reorganization augment effects neurorehabilitation. However, non-invasive paradigms limited by their depth focality trade-off function that does not allow target deep key structures critically important...
Visual motion discrimination involves reciprocal interactions in the alpha band between primary visual cortex (V1) and mediotemporal areas (V5/MT). We investigated whether modulating phase synchronization using individualized multisite transcranial alternating current stimulation (tACS) over V5 V1 regions would improve discrimination. tested 3 groups of healthy subjects with following conditions: (1) In-Phase V1alpha-V5alpha tACS (0° lag), (2) Anti-Phase (180° lag) (3) sham tACS. Motion EEG...
The use of TMS-EEG coupling as a neuroimaging tool for the functional exploration human brain recently gained strong interest. If this directly inherits fine temporal resolution from EEG, its spatial counterpart remains unknown. In study, we explored by evaluating minimal distance between two stimulated cortical sites that would significantly evoke different response dynamics. TMS evoked responses were mapped on sensorimotor region in twenty participants. stimulation grid was composed nine...
The literature investigating the effects of alpha oscillations on corticospinal excitability is divergent. We believe inconsistency in findings may arise, among others, from electroencephalography (EEG) processing for brain-state determination. Here, we provide further insights cortical and quantify impact different EEG processing.
Abstract Homonymous Hemianopia (HH), a common visual impairment resulting from occipital lobe lesions, affects significant number of stroke survivors. Intensive perceptual training can foster recovery, possibly by enhancing surviving pathways. This study employed cortico-cortical paired associative stimulation (ccPAS) to induce plasticity within the residual and bi-directional primary cortex (V1) - middle temporal area (MT) pathways in patients. We used ccPAS, which is thought tap into...
Despite recent improvements, complete motor recovery occurs in <15% of stroke patients. To improve the therapeutic outcomes, there is a strong need to tailor treatments each individual patient. However, lack knowledge concerning precise neuronal mechanisms underlying degree and course its differences, especially view brain network properties despite fact that it became more clear disorder. The TiMeS project longitudinal exploratory study aiming at characterizing phenotypes large,...
Cortico-cortical paired associative stimulation (ccPAS), which repeatedly pairs single-pulse transcranial magnetic (TMS) over two distant brain regions, is thought to modulate synaptic plasticity. We explored its spatial selectivity (pathway and direction specificity) nature (oscillatory signature perceptual consequences) when applied along the ascending (Forward) descending (Backward) motion discrimination pathway. found unspecific connectivity increases in bottom-up inputs low gamma band,...
