Rice, W. … Webb12 apr. 2024 · This disagreement might be due to the fact that ours is a model of inter-cortical wave propagation, whereas it has been argued that travelling waves in the scalp are mediated by an intra-cortical mechanism . In fact, travelling waves in the cortex are usually observed not at the whole-brain level but localized in smaller regions [5, 75, 76].
Webb10 mars 2024 · Here, a train of pulses is applied over a few seconds to entrain the cortex into a triggered seizure, and confirm its expected, patient-typical clinical correlates. 67 The ability to trigger a seizure at the suspected seizure onset zone and not in other cortices contributes to the localizing value of actively probing the epileptic brain. WebbHere, we report ampere simplified demarcation protocol this yields electrophysiologically mature iPSC-derived cortical lineage neuronal nets without the need for astrocyte co-culture or specialized media. This protocol generates a consistent 60:40 ratio of neurons and astrocytes that arise from a common forebrain nerve-related ancestral.
