Chapter 40: Sensation, Perception, and Neural Systems

The nervous system is a computational architecture on τ³, with neurons as typed nodes in a directed graph and synapses as weighted edges. Each sensory modality—vision, audition, olfaction, gustation, somatosensation—serves as an input channel to this neural τ³ computer. Perception integrates these raw signals into interpreted representations through feature extraction and pattern recognition, realized across diverse neural architectures from invertebrate ganglia to the vertebrate central nervous system.
