The somatosensory cortex doesn't integrate mixed bilateral inputs, as partially uncrossing projections from the whiskers duplicates their representation by segregating lateralized inputs from each side of the head.

Dorsal raphe Pet1 neurons are molecularly heterogeneous, comprising as many as fourteen distinct subtypes that show biased cell body distributions across dorsal raphe subdomains.

The transcription factor Olig3 safeguards the correct specification of early born cerebellar neuron derivatives and curtails an inhibitory interneuron differentiation program.

Chromatin remodeler Hmga1 has two separable functions in neural crest development, first neural crest specification at the neural plate border and later in Wnt-dependent emigration from the neural tube.

The human Fibrodysplasia-Ossificans-Progressiva BMP-receptor mutant signals in zebrafish in the absence of ligand-binding, displays BMP ligand-responsive hyperactivity, neither requiring other type-I-BMP receptors, unlike wild-type, challenging views of the pathological mechanism.

New genetic tools have allowed researchers to compare how the brainstem auditory and vestibular nuclei develop in embryonic chicks and mice.

The dorsal raphe nucleus contains transcriptionally diverse cell classes that include subtypes of serotonergic neurons with distinct molecular and anatomical signatures.

The RNA-binding protein NOVA2 coordinately regulates the alternative splicing of key components in axon guidance and outgrowth pathways, with severe functional consequences.

Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.
