Minamisawa G, Kwon S, Chevee M, Brown S, O Connor D. A Non-canonical Feedback Circuit for Rapid Interactions between Somatosensory Cortices. Cell Rep. 2018;23:2718-2731.e6 pubmed publisher
..Thus, a non-canonical feedback circuit, originating in layer 4 of S2, rapidly modulates early tactile processing. ..
Finkel E, O Connor D. Learning Recruits Higher Cortical Areas into Rapid Sensorimotor Streams. Neuron. 2018;97:1-2 pubmed publisher
..A new study in this issue of Neuron (Le Merre et al., 2017) uncovers learning-related recruitment of higher cortical areas into the rapid sensory processing stream that links a whisker stimulus to rewarded action. ..
Severson K, O Connor D. Active Sensing: The Rat's Nose Dances in Step with Whiskers, Head, and Breath. Curr Biol. 2017;27:R183-R185 pubmed publisher
..Active sampling of touch and smell involves coordinated movements first observed in the rat half a century ago. A new study has unveiled the elegant choreography of this facial and head motion during tactile and olfactory exploration. ..
Severson K, Xu D, Van de Loo M, Bai L, Ginty D, O Connor D. Active Touch and Self-Motion Encoding by Merkel Cell-Associated Afferents. Neuron. 2017;94:666-676.e9 pubmed publisher
..Thus, Merkel afferents send to the brain multiplexed information about whisker position and surface features, suggesting that proprioception and touch converge at the earliest neural level. ..
Kwon S, Tsytsarev V, Erzurumlu R, O Connor D. Organization of orientation-specific whisker deflection responses in layer 2/3 of mouse somatosensory cortex. Neuroscience. 2018;368:46-56 pubmed publisher
..Our results shed light on L2/3 organization in mouse somatosensory cortex, and lay a foundation for dissecting circuit mechanisms of perceptual learning and decision-making during orientation discrimination tasks. ..
