Sensory Systems
Specialized biological networks that detect stimuli from an organism's environment and convert them into electrical signals the nervous system can interpret are sensory systems, spanning vision, hearing, touch, taste, and smell.
Overview
Each system performs transduction — photoreceptors absorb photons, cochlear hair cells respond to mechanical waves, and chemoreceptors bind molecules — then relay signals through afferent pathways to cortical processing regions that encode stimulus intensity, frequency, and modality.
Why it matters
Sensory research has profoundly shaped neuroscience and medicine, guiding treatments for congenital deafness and peripheral neuropathy, while foundational discoveries about topographic mapping and receptor adaptation continue to advance our understanding of perception and cognition.
