- claim_text
The transcription factor RORβ is required in mouse cortex for layer-4 aggregation into barrels and for thalamocortical-afferent segregation, and its loss disrupts L4 gene expression and chromatin accessibility — down-regulating L4 genes and up-regulating L5 genes — indicating that L4 transcriptional identity directly underlies L4 cytoarchitecture.
