ABSTRACT
The several cortical populations project in turn to further cell populations, and those to populations further still, until eventually the receiving population consists of motor cells, cells whose patterned activity is transformed by the muscle spindles into coherent bodily movement of some kind. Thus do we complete the basics of our new conception of how the nervous system works, from perception through cognition to organized behavior. It is here a stick-figure portrait, to be sure, but you will find it richly articulated in many directions in the literature. Patricia Churchland’s and Terry Sejnowski’s (1992) book provides an accessible and richly illustrated entry into the current state of research. My (1989) book attempts to draw out some of its consequences for epistemology and the philosophy of science.
