Definition of Divisive Normalization (DN)

Divisive Normalization (DN) is a perceptual mechanism that occurs in the early stages of visual processing. It refers to the phenomenon where the activity level of a neuron is divided by the sum of the activity levels of neurons within its receptive field. This normalization process allows for the effective representation of visual stimuli by adjusting the strength of neural responses to different inputs. DN is widely observed not only in visual cortex but also in other sensory modalities such as audition and touch. The objective of DN is to maintain consistent response characteristics across a wide range of stimulus conditions, thus enabling the brain to effectively encode and process sensory information. This phenomenon is often described using the concept of gain control, where DN acts to regulate the gain of neural responses in a way that optimizes the sensitivity and discriminability of sensory signals. Understanding the mechanisms and functional implications of Divisive Normalization provides important insights into the neural basis of perception and the mechanisms underlying information processing in the brain.
