TALK ABSTRACT
Life was solving problems in metabolic, genetic, physiological, and anatomical spaces long before brains and nervous systems appeared. In this talk, I will describe remarkable capabilities of cell groups as they create, repair, and remodel complex anatomies. Anatomical homeostasis reveals that groups of cells are collective intelligences; their cognitive medium is the same as that of the human mind: electrical signals propagating in cell networks. I will explain non-neural bioelectricity and the tools we use to track the basal cognition of cells and tissues and control their function for applications in regenerative medicine. I will conclude with a discussion of our framework based on evolutionary scaling of intelligence by pivoting conserved mechanisms that allow agents, whether designed or evolved, to navigate complex problem spaces.
