To investigate the sensory contributions of barrel cortex, the authors estimate spatiotemporal receptive fields by reverse correlation of multi-whisker stimulation to synaptic inputs. Complex stimuli revealed dramatically sharpened receptive fields, largely due to adaptation, and suggest the potential importance of surround facilitation through adaptation for discriminating complex shapes and textures during natural sensing.
