Objective To observe the divergent axon collaterals from hippocampus to hypothalamus and lateral septal nuclei in the rat.Method By means of fluorescein double label,primuline(Pr) and bisbenzimide(Bb) were injected into rat right hypothalamus and left lateral septal nuclei respectively,observing the retrograde labeled cells in hippocampus.Result Pr single labeled cells,Bb single labeled cells and Pr/Bb double labeled cells were found in bilateral hippocampi.Conclusion The refrograde double labeled cells in the hippocampi may divergently projected to the hypothalamus and lateral septal nuclei. |
