Neurosensorielle

Neurosensorielle is an adjective used in French to designate phenomena, processes or systems that relate to the nervous system and sensation. In neuroscience, it concerns the reception, transmission and processing of sensory information by the nervous system, from peripheral receptors to cortical areas. The term encompasses all sensory modalities, including vision, hearing, touch, taste, smell, and balance, as well as proprioception and other forms of somatosensation, and how these signals are integrated to form perception and guide behavior.

Key concepts in neurosensorielle include transduction (the conversion of sensory stimuli into neural signals), neural coding and the rate of neuronal firing, and the organization of sensory pathways such as the somatosensory, visual, and auditory systems. Multisensory integration—how the brain combines information from different senses—and the plasticity of sensory systems across development and experience are central themes. The field also studies disorders that affect neurosensorielle processing, including sensory loss, neuropathies and cortical processing abnormalities.

Applications span basic research and clinical practice. Diagnostic methods such as electrophysiology, functional imaging and psychophysics assess sensory function, while rehabilitation aims to restore or substitute sensation. Technologies include cochlear implants, retinal prostheses, neural prosthetics with sensory feedback, and sensory substitution devices. The study of neurosensorielle intersects with neurophysiology, cognitive neuroscience and rehabilitation sciences, and informs efforts to augment perception and interaction with the environment through new interfaces and therapies.
