Vicente Raja examines how ecological psychology can inform neuroscience. The discussion connects affordances, direct perception, information and resonance with embodied approaches to brains and minds, then considers plant behaviour. He also explores how shared conceptual motifs can support research across disciplines without requiring identical definitions.

Arvind Kumar examines how spikes convey information and how researchers distinguish competing accounts of neural coding.

In recent years it has become increasingly clear that (Shannon) information is a central resource for organisms, akin in importance to energy. Any decision that an organism or a subsystem of an organism takes involves the acquisition, selection, and processing of information and ultimately its concentration and enaction. It is the consequences of this balance that will occupy us in this talk. This perception-action loop picture of an agent's life cycle is well established and expounded especially in the context of Fuster's sensorimotor hierarchies. Nevertheless, the information-theoretic persp

Sara Imari Walker and Sean Carroll explore how life differs from other complex physical systems and whether information and computation help explain its emergence. Beginning around 6:38, Walker discusses biological homochirality: the preference for one molecular handedness, the roughly balanced mixtures produced without biology, and chemical symmetry breaking. Their wider conversation considers definitions of life, prebiotic chemistry, emergence, and the search for life beyond Earth.
