A radial map of multi-whisker correlation selectivity in the rat barrel cortex
Résumé
In the barrel cortex, several features of single-whisker stimuli are organized in functional
maps. The barrel cortex also encodes spatio-temporal correlation patterns of multi-whisker
inputs, but so far the cortical mapping of neurons tuned to such input statistics is unknown.
Here we report that layer 2/3 of the rat barrel cortex contains an additional functional map
based on neuronal tuning to correlated versus uncorrelated multi-whisker stimuli: neuron
responses to uncorrelated multi-whisker stimulation are strongest above barrel centres,
whereas neuron responses to correlated and anti-correlated multi-whisker stimulation peak
above the barrel–septal borders, forming rings of multi-whisker synchrony-preferring cells.
