Wayne Sossin Aplysia: If We Understand the Cellular Mechanisms Underlying Sensation and Learning, What Do We Need Consciousness for?
Abstract: Aplysia is a model system for defining the relationship between neuronal plasticity and behavior. Indeed, many of the circuits underlying Aplysia's simple behaviors are understood, as well as how the animal can change those circuits after experience. Moreover, it is beginning to be understood how biogenic amine and neuropeptide pathways can activate or inhibit distinct motor programs to bias the animals decisions on what to do. I will explore, given the limited number of neurons in Aplysia, whether the additional pathways are present that would lead to the complex feedback systems that are probably required for consciousness.
