  • Imaging of brain structures in living mice reveals that learning new tasks leads to persistent remodelling of synaptic structures, with each new skill associated with a small and unique assembly of new synapses.

  • Whether the posterior medial (POm) thalamic nucleus processes whisking kinematics was not clear from studies in head-fixed rodents. By studying freely moving mice, here authors demonstrate that the POm does encode whisker kinematics. Additionally, they show that both POm and the ventroposterior medial (VPM) thalamic nuclei process and can influence head kinematics.

  • Touch information is conveyed by a receptorless whisker hair to the follicle mechanoreceptors that provide input to the brain. Here the authors show that information processing goes on even at the level of the whisker, which suggests a role for pre-neuronal morphological computation in active vibrissal touch.

  • Wallach et al. use closed-loop artificial whisking in anesthetized rats to show that vibrissal mechanoreceptors extract phase information from on-going whisker kinematics in a frequency- and amplitude-invariant manner. Brainstem paralemniscal neurons preserve this phase information while filtering out information about whisker offset; lemniscal neurons preserve both types of information.

  • Demonstrating how specific motor signals modulate sensory processing in the rat vibrissal system, a new study in this issue shows that motor signals first attenuate and then amplify afferent sensory signals.

  • It is unknown how humans establish stable visual percepts despite the incessant motion of their eyes. Here the authors report that visual judgments of spatial relations incorporate fine-scale motor knowledge of eye position.

  • Many animals use their whiskers to collect information about the environment. Diamond and colleagues explain how the brain creates a neuronal representation of the location and identity of objects from sensory signals and argue that this involves integration of knowledge about the self-generated whisker motion.
