Normalization in human somatosensory cortex

The normalization model was initially proposed to explain stimulus-evoked responses of individual neurons in primary visual cortex (V1) (Carandini et al. 1997; Carandini and Heeger 1994; Heeger 1992). The model’s defining characteristic is that the response of each neuron is divided by a factor that ...
