| Type | MGI:General | Description | more PLAP-labeled axons enter the thalamus, external capsule, and anterior commissure, while fewer labeled axons are seen in the caudal cerebral peduncle, few or no labeled axons are found in the pyramidal tract, and no labeled axons are seen in the corticospinal tract PLAP-labeled axons fail to cross the midline and instead accumulate into Probst bundles or turn ventrally into septum most cortical layer 5 neurons fail to extend axons into subcortical targets and neurons from the somatosensory and visual cortex extend fewer axons into the superior colliculus and no axons into the pyramidal decussation or corticospinal tract |
