The growth of neurites (axon and dendrite) should be appropriately regulated by their interactions in the development of nervous systems where a myriad of neurons and their neurites are tightly packed. We show here that mammalian seven-pass transmembrane cadherins Celsr2 and Celsr3 are activated by their homophilic interactions and regulate neurite growth(More)
The goal of this research is to develop a new type of haptic interface termed "active polyhedron", which realizes a physical human-machine interaction with virtual continuum objects in PCs. Active polyhedrons are polyhedron-shaped linkage mechanisms. In this paper, we deal with an active icosahedron consisting of 30 intelligent cylinders, which were(More)
