Sensory Processing

Definition

Sensory processing refers to the way in which the nervous system receives, interprets, and organizes sensory information from the environment. This process is critical for allowing organisms to respond effectively to their surroundings, integrating inputs from various sensory modalities such as sight, sound, touch, taste, and smell. It plays a key role in how information is encoded and utilized in both biological systems and artificial neural networks.
