摘要：Walking is a complex motor programme involving coordinated and distributed activity across the brain and the spinal cord. Halting appropriately at the correct time is a critical component of walking control. Despite progress in identifying neurons driving halting1-6, the underlying neural circuit mechanisms responsible for overruling the competing walking state remain unclear. Here, using connectome-informed models7-9 and functional studies, we explain two fundamental mechanisms by which Droso...

摘要：Avulsing rivers create new pathways on the floodplain and the associated flooding can profoundly affect society(1-4). River avulsions are thought to occur when the water column becomes perched above the floodplain5 or when the slope down the flanks of the channel provides a steeper descent than the existing river channel(6,7). We test these classical ideas by quantifying the topography around avulsing rivers and show that these mechanisms, historically invoked separately, work together. Near c...
