Reconstructing cortical surfaces from structural magnetic resonance imaging (MRI) is a prerequisite for surface-based functional and anatomical image analy

Libet demonstrated that a substantial duration (>0.5–1.0s) of direct electrical stimulation of the surface of a sensory cortex at a threshold or liminal current is required before a subject can experience a percept. Libet and his co-workers originally proposed that the result could be due eithe...
For demonstrating how the 80 emotion categories were represented in the cortical surface, we visualized a continuous semantic space of the emotion representation and mapped it on the cortical surface. We found that the emotion categories were changed from unimodal to transmodal regions on the cortical...
sensory stimuli of a given modality will desynchronise localised areas of the cortical surface. Various feature-extracting functions have been found to map on the surface of the cortex, and indeed different stimuli are found to evoke distinct electrical “signatures” on the cortical surface and mor...
of lowering SNR. On the other hand, while a small surface coil can only cover a small anatomical region, i.e., field of view (FOV), the signal acquired generally has higher SNR compared to a volume coil. By arranging multiple mutually decoupled surface coils surrounding the brain and...
The mechanical stimulation was stretch of an isolated intercostal space. The sensorimotor cortex was mapped with a surface ball electrode. Primary cortical evoked potentials (CEP) were found in area 3a of the sensorimotor cortex with mechanical and electrical stimulation. The CEP was elicited with ...
