  • It is an open question whether choice signals in primary sensory areas have a causal influence on an animal’s perception. Here, the authors show that early sensory representations in the neocortex can be selectively manipulated to bias perception during discrimination behavior.

  • During adaptation, neocortical responses change as a result of repeated sensory stimulation, but it's unclear how this affects perception. Here the authors use optogenetics to mimic sensory evoked cortical responses with or without adaptation. They find adaptation impairs frequency discrimination but enhances change detection during whisker stimulation.

  • The authors explore how sensory maps are reshaped by experience in vivo, using chronic two-photon calcium imaging to follow whisker-evoked activity of individual layer 2/3 neurons in adult mouse barrel cortex over weeks. By first measuring activity with whiskers intact and then with continued trimming of all but one whisker, they describe how the redistribution of population activity underlies large-scale cortical remapping.

  • In rodents, descending corticospinal tracts can be rerouted to innervate new targets after a spinal cord injury. Here, Ghosh et al. show that such anatomical rearrangement in the injured spinal cord is accompanied by sensory remapping at the cortical level.
