Cortical Substrate of Haptic Representation
Abstract
The focus of our research has been on the role and mechanisms of memory in motor control. Based on our experience and data from primates, we have developed computational models of short-term active memory. Such models may have technological interest and applications because this kind of memory is an essential feature of any motor control system, biological or mechanical. As far as I know, the neurally based and neurally testable modeling of the function of memory networks is unique among ONR-sponsored programs. Research in our laboratory led to the discovery of memory cells in the cerebral cortex of the monkey. Over a period of several years, extensive studies of neuronal activity and reversible--cryogenic--inactivation in monkeys performing memory tasks have provided us with theoretical framework of perceptual memory. Within that framework, memory cells are the constituents of widely distributed cortical networks which, by mechanisms yet unknown, are activated above certain thresholds and kept active, for seconds or minutes, to retain information for prospective motor action
