Number of axons in the right and left optic nerves of right-pawed and left-pawed rats: a stereologic study.
OBJECTIVE
To compare the number of axons in the right and left optic nerves of right- and left-pawed rats.


METHODS
In this study, optic nerve samples were obtained from right- and left-pawed rats and axon numbers of optic nerves and vice versa were stereologically and histologically evaluated.


RESULTS
In the right-pawed rats, more axons were found in the right optic nerve than in the left optic nerve, and left-pawed rats had more axons in the left optic nerve than in the right optic nerve.


CONCLUSIONS
The paw preference is associated with eye dominance and the number of axons in the ipsilateral optic nerve.
