The neurons in layer IV of the mouse somatosensory cortex are arranged in a remarkably consistent pattern of multicellular cytoarchitectonic units called "barrels." Each barrel is known to be related, in a one to one manner, to a contralateral whisker or vibrissa on the animal's face. In this study we have examined Golgi-impregnated neurons that comprise(More)
A central issue in the design of multiprocessor systems is the interconnection network which provides communications paths between the processors. For large systems, high bandwidth interconnection networks will require numerous 'network chips' with each chip implementing some subnetwork of the original larger network. Modularity and growth are important(More)
Philip Heidelberger (M'82) received the B.A. degree in mathematics from Oberlin College, Oberlin, OH, in 1974 and the Ph.D. degree in operations research from Stanford University, Stanford, CA, in 1978. He has been a Research Staff member at the IBM Thomas J. Watson Research Center, Yorktown Heights, NY, since 1978. His current research interests include(More)
A new computer system organization and implementation is described and its application to problems in both clinical and research laboratory biomedical applications is outlined. This system, called a Conjoined Computer System to emphasize the idea of computer coordination, consists of a few storedprogram computers, each with a fixed assigned task, and(More)
This paper describes the teaching of computer design using a new and quite unusual hardware aid, macromodules. Of all the new areas emerging in Computer Science the teaching of computer structures, from an engineering viewpoint, has continually challenged the professional educator. This has in a sense presented a dilemma to him: for digital computer system(More)
