Cortical circuitry mediating inter-areal touch signal amplification

The paper investigates how topographically matched subregions of vS1 and vS2 interact during whisker touch, finding that a sparse population of broadly tuned neurons in superficial layers amplifies touch responses between these areas.

Sparse and distributed cortical populations mediate sensorimotor integration

The paper investigates touch-motor interactions in mouse somatosensory and motor cortices, finding that sparse, broadly tuned neurons mediate these interactions through specialized population dynamics.

Microstimulation of sensory cortex engages natural sensory representations

This study shows that microstimulation of sensory cortex activates natural sensory representations more than expected by chance, and repeated co-stimulation enhances this effect.

Columnar scale lesions in barrel cortex degrade tactile discrimination but not detection

The paper shows that columnar scale lesions in mouse vS1 impair tactile discrimination but not detection.
