(see article e0156252026)
The corpus callosum contains axonal projections that connect the cortical hemispheres of the brain. These projections originate from layer 2/3 pyramidal neurons and target corresponding brain areas in the opposite, or contralateral, hemisphere. Perez-Otaño and colleagues explored the molecular determinants of this distinct innervation pattern in mice. The authors used in utero electroporation to label axons and dendrites of layer 2/3 neurons …
