Carandini and Heeger model

The Carandini and Heeger model describes how the brain processes visual information, particularly in the visual cortex. It explains that neurons respond not just to raw stimuli but to a combination of features, with their responses influenced by both the input signal and surrounding context. The model emphasizes that neural activity results from a balance between excitation (activation) and inhibition (suppression), allowing the brain to adapt to different visual environments. This framework helps us understand phenomena like contrast perception and how we interpret complex visual scenes efficiently.
