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.

Neural correlates of somatosensory target detection are restricted to secondary somatosensory cortex, whereas activity in insular, cingulate, and motor regions reflects stimulus uncertainty and overt reports.

Secondary thalamic nuclei may provide stronger, longer-lasting input to superficial layers of primary sensory cortex than other cortical areas can.

Secondary somatosensory and visual thalamus monitor behavioral state, rather than movement, and may exist to alter cortical activity accordingly.

Salient or behaviorally relevant stimuli, regardless of their modality, robustly activate both higher-order somatosensory and visual thalamic nuclei.

Oligodendrocyte precursor cells receive brain-wide, circuit-specific intracortical, coritcocortical and thalamocortical synaptic inputs.

Transient expression of Nrp1 is required in postnatal stages for terminal arborization and innervation of secondary areas during the development of somatosensory callosal circuits.

NMDAR receptors act in regulating axon guidance of somatosensory callosal projections in early postnatal life and the expression of EPHB2 receptors in target cells.

The most comprehensive neuroanatomical atlas on the expression of three glycoprotein hormone receptors, namely, TSHRs, LHCGRs, and FSHRs, was mapped using RNAscope, a technology that allows the detection of mRNA at single-transcript level.

A new microscopy system allows the activity of interconnected neurons in different brain regions to be measured simultaneously.
