Somatosensory Cortical Neurons Decode Tactile Input Patterns and Location from Both Dominant and Non-dominant Digits

Enander and Jörntell record spike responses in neocortical neurons in primary somatosensory cortex provided with tactile inputs from non-adjacent digits. Regardless of whether the neurons were located in specific digit-dominated subregions, each neuron decoded the tactile inputs from either digit as well as the input location.
