FREEMAN'S INTENTIONAL NEURODYNAMICS.

In this commemoration of Walter Freeman's life and legacy, we review some his key contributions to the field of cognitive neuroscience. We elaborate on his groundbreaking contribution to neural aspects of intentionality, what he called intentional neurodynamics. We describe the conceptual framework of intentional neurodynamics and its neurophysiological manifestations. We conclude with the outline of Freeman K (Katchalsky) sets, a hierarchical model of brain structure, dynamics, and functions, which provide a suitable mathematical and computational framework to grasp essential aspects of intentionality.
