lateral inhibition
Neural circuit mechanism where active neurons inhibit their neighbors to enhance contrast.
Full Definition
Lateral inhibition is a fundamental neural circuit organization in which activated neurons suppress the activity of neighboring neurons through inhibitory connections. This mechanism enhances contrast and sharpens the representation of stimuli by reducing background activity and emphasizing differences between adjacent regions. Lateral inhibition is prominent in sensory systems, including the retina, where it contributes to edge detection and contrast enhancement in vision. The principle also applies to other sensory modalities and higher-order processing areas. Understanding lateral inhibition is crucial for comprehending how neural circuits process information and create selective responses to specific features of sensory input.
