A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.

Focal optogenetic stimulation strengthens functional connectivity between primary somatosensory and motor cortices in macaques, in a manner consistent with a Hebbian model of stimulus-driven plasticity.
Parvalbumin positive GABAergic neurons in the ventral zona incerta receive input from somatosensory cortex and enhance sound-induced flight behavior, which underlies a cross-modality facilitation of defensive behavior by somatosensory input.

A new spinal somatosensory preparation is described which enables fine control of sensory input and the ability to manipulate spinal interneurons while recording from spinal projection neurons.
Early in development, before neurons in primary motor cortex are involved in motor control, they undergo a rapid transition in how they process sensory information following sleep and wake movements.
Snout-to-snout contact modulates the response of rat auditory cortex to calls from other animals, indicating that the multisensory nature of social interaction is directly represented in the rat brain.
A muscle-derived Wnt signal promotes dendritic branching of somatosensory neurons in response to a concurrent deficiency in vitamins, minerals, and cholesterol.
A spatial analysis of auditory and non-auditory properties of excitatory and inhibitory neurons in the mouse dorsal inferior colliculus defines the border between the lateral and the dorsal cortex.
