Rana computatrix: progress report, 1984

This paper describes an approach to analyzing mechanisms of visuomotor coordination that is twofold: top-down, to offer a coordinated control program of interacting schemata (functional units, underlying behavior, which can be activated in different combinations) to achieve behavior noted by neuroethologists; and bottom-up, to provide detailed models of neural networks that are consistent with known anatomy and physiology, but that involve additional assumptions, amenable to experimental testing, to yield a network capable of exhibiting appropriate behavior. Rana computatrix, an evolving series of models of frog and toad visuomotor coordination, is described.
