Adaptive neural networks in movement control: Some persistent concerns: Reaction to Bullock and Grossberg, 1991

Abstract

The Bullock and Grossberg VITE (vector-integration-to-endpoint) and FLETE (factorization-of- length-and-tension) models are an attempt to stimulate the control of human voluntary movement. As successful as these models appear to be, a number of concerns regarding them are raised. These concerns come from three broad areas, namely: (a) the lack of appreciation for the contributions to the control of human voluntary movement, by those cerebellar elements not currently considered in the Bullock and Grossberg model, (b) the general purpose and direction that models like those put forward by Bullock and Grossberg provide, and (c) the level at which such information processing models may be understood.
