Implication
Experimental examination reveals that clonally related neuron dispersion occurs in the rat neocortex, indicating post-neurogenesis area specification.
Key Points
- This research investigates the spatial distribution of neuronal clones across functional regions of the cerebral cortex during embryonic development.
- Used retroviral-mediated transfer to mark clonally related neocortical cells.
- Infected rat brains with distinct viruses to create a library of genetic markers.
- Utilized polymerase chain reaction to amplify single viral genomes for analysis.
- Clonally related neurons were found dispersed widely across different functional areas of the cortex.
- Suggests that the specification of cortical areas occurs after the process of neurogenesis.
