In the rodent vibrissal system, active sensation and sensorimotor integration are mediated in part by connections between barrel cortex and vibrissal motor cortex. Little is known about how these structures interact at the level of neurons. We used Channelrhodopsin-2 (ChR2) expression, combined with anterograde and retrograde labeling, to map connections between barrel cortex and pyramidal neur...
Comparison of cerebral activation between motor execution and motor imagery of self-feeding activity
Motor imagery is defined as an act wherein individual contemplates a mental action of motor execution without apparent action. Mental practice executed by repetitive can improve performance simultaneous sensory input or overt output. We aimed to investigate cerebral hemodynamics during and self-feeding activity using chopsticks. This study included 21 healthy right-handed volunteers. The task c...
Recent anatomic and functional data radically changed our ideas about the organization of the motor cortex in primates. Contrary to the classic view, the motor cortex does not consist of two main areas, primary and supplementary motor areas, but of a mosaic of cortical areas with specific connections and functional properties.
Somatotopic distribution of motor cortex and sensory fibers is theoretically fully understood. We present a case of stroke, mimicking peripheral palsy, with finger paralysis attributed to cortical lesion. The patient’s brain MRI may be useful to further understand the somatotopic representation of fingers in precentral and postcentral gyrus.
Introduction: Based on the literature, unihemispheric concurrent dual-site anodal transcranial Direct Current Stimulation (a-tDCSUHCDS) of primary Motor cortex (M1) and Dorsolateral Prefrontal Cortex (DLPFC) would be more efficient than conventional a-tDCS of M1 to induce larger and longer-lasting M1 corticospinal excitability. The main objective of the present study was to compare the effects ...
