How developing axons in the corpus callosum (CC) achieve their homotopic projection to the contralateral cortex remains unclear. We found that axonal position within the CC plays a critical role in this projection. Labeling of nearby callosal axons in mice showed that callosal axons were segregated in an orderly fashion, with those from more medial cerebral(More)
Apparent motion quartet is an ambiguous stimulus that elicits bistable perception, with the perceived motion alternating between two orthogonal paths. In human psychophysical experiments, the probability of perceiving motion in each path is greatly enhanced by a brief exposure to real motion along that path. To examine the neural mechanism underlying this(More)
Nested timed automata(NeTAs), proposed by Li et al., are a pushdown system whose stack symbols are timed automata (TAs). With this formal models, we can model and analyze complex real-time frameworks with recursive context switches. The reachability problem of NeTAs is proved to be decidable, via encoding NeTAs to dense timed pushdown automata (DTPDAs).(More)
Directional flow of membrane components has been detected at the leading front of fibroblasts and the growth cone of neuronal processes, but whether there exists global directional flow of plasma membrane components over the entire migrating neuron remains largely unknown. By analyzing the trajectories of antibody-coated single quantum dots (QDs) bound to(More)
Updatable timed automata (UTAs) proposed by Bouyer, is an extension of timed automata (TAs) having the extra ability to update clocks in a more elaborate way than simply reset them to zero. The reachability of UTAs is generally undecidable, which can be easily gained by regarding a pair of clocks as updatable counters. This paper investigates a(More)
Binocular rivalry is a fascinating perceptual phenomenon that has been characterized extensively at the psychophysical level. However, the underlying neural mechanism remains poorly understood. In particular, the role of the early visual pathway remains controversial. In this study, we used voltage-sensitive dye imaging to measure the spatiotemporal(More)
