Sensory Neuroprostheses: Restoring Vision and Other Senses

This lecture introduces the fundamentals of sensory neuroprostheses, focusing on the design and implementation of devices aimed at restoring vision, hearing, and balance. The instructor discusses the physiology of sensory systems and the various neurotechnologies available for providing missing sensory information. Key topics include the structure and function of the visual system, the role of the retina, and the challenges associated with visual prostheses. The lecture emphasizes the importance of encoding strategies, which translate artificial sensory input into a format the nervous system can understand. The instructor also highlights the significance of modularity and recycling technology in developing effective neuroprosthetic devices. Various types of visual prostheses, including retinal and cortical implants, are explored, along with their respective advantages and limitations. The discussion extends to the broader implications of sensory neuroprostheses for individuals with sensory impairments, particularly the elderly and those affected by conditions such as macular degeneration and glaucoma. Overall, the lecture provides a comprehensive overview of the current state of sensory neuroprosthetics and future directions in the field.
