Abstract:
Divergent axon collaterals from forebrain and brainstem to the dorsal hippocampus in the rat were examined by means of HRP method and fluorescent retrograde double labeling method.HRP solution was injected into the left or right dorsal htppocampus of 3 rats. HRP labeled cells were observed in the bilateral medial parts of medial septal areas, vertical limbs of the diagonal band of Broca, supramammillary nuclei, submammillothalamic nuclei, superior central nucleus and locus ceruleus.PI and Bb solution were injected into the left and right hippocampus of 3 rats separately. Many retrograde double labeled cells were found in the nuclei mentioned above.The results indicate that the retrograde double labeled ceils in these nuclei may divergently projected to both the left and right dorsal hippocampi. They play an important role in harmonizing the activity of bilateral hippocampi.
