| Open AccessOngoing movement controls sensory integration in the dorsolateral striatum
The basal ganglia process sensory and motor related information, but it is not known how movement affects sensory integration. Here, the authors show using in vivo whole-cell recordings that striatal neurons respond to both sensory stimuli and spontaneous whisking and that sensory responses are attenuated by whisking.

| Open AccessLearning enhances encoding of time and temporal surprise in mouse primary sensory cortex
Activity in the superficial layers of the sensory cortex is believed to be largely driven by incoming sensory stimuli. Here the authors demonstrate how learning changes neural responses to sensations according to both behavioral relevance and timing, suggesting a high degree of non-sensory modulation.

| Open AccessSpatiotemporal refinement of signal flow through association cortex during learning
Learning is a dynamic process involving many cortical areas. Here, using cortex-wide imaging, the authors show that in mice learning to discriminate between two textures a distinct task related signal flow is enhanced involving a specific association area whereas other association areas are suppressed.

| Open AccessSuperior colliculus modulates cortical coding of somatosensory information
While there is no direct pathway from the superior colliculus to the cortex, the authors find that the superior colliculus modulates sensory-evoked responses in the somatosensory cortex. This modulation by the superior colliculus is mediated via a powerful di-synaptic pathway through the thalamus.

| Open AccessHighly structured, partner-sex- and subject-sex-dependent cortical responses during social facial touch
Touch is an important sensory modality during social encounters. Here the authors report that during naturalistic social encounters in rats, the cortical activity in widespread areas at the level of single neurons is modulated by sociosexual characteristics such as the subject and partner sex.

| Open AccessRich spatio-temporal stimulus dynamics unveil sensory specialization in cortical area S2
Sensory tuning properties of neurons in the secondary whisker somatosensory cortex (wS2) are not well understood. Here, the authors report that wS2 neurons supralinearly integrate concurrent multi-whisker input with larger temporal windows than primary somatosensory cortex.

| Open AccessCortical modulation of sensory flow during active touch in the rat whisker system
During active touch, sensory responses to object touch are gated at the level of thalamus and cortex. Here, the authors report gating at the level of the brainstem and show that an intact somatosensory cortex is essential for this response modulation.

| Open AccessA radial map of multi-whisker correlation selectivity in the rat barrel cortex
Barrel cortex contains a functional map of whiskers but how neuronal activity maps multi-whisker inputs has not been studied. Here the authors show that while uncorrelated multi-whisker stimuli activate barrel neurons, correlated multi-whisker inputs activate neurons in a ring at the barrel-septa boundary
