Leanchoilia superlata is one of the best known arthropods from the middle Cambrian Burgess Shale of British Columbia. Here we re-describe the morphology of L. superlata and discuss its possible autecology. The re-description follows a standardized scheme, the descriptive matrix approach, designed to provide a template for descriptions of other megacheiran(More)

Today we know that small circuits are quite complex and show dynamics that reveal many fundamental principles of circuit function. These principles provide a library of circuit mechanisms that are almost certainly used in all large brains.(More)
