Septal Unit Responses to Hippocampal and Hypothalamic Stimulation in the Chloralose-Anaesthetized or Cerveau Isolé Cat
There is substantial anatomic evidence for projections to septal nuclei from the hippocampus (2,7) via the fimbria-fornix system, and from the tegmentum and hypothalamus via the medial forebrain bundle (2,14,15). On the basis of these inputs, the septal area has been described as a region of confluence, convergence and correlation between neural activities ascending in the medial forebrain bundle (MFB) and descending from the limbic system (9). By implication, neurones of the septal nuclei should give evidence of interactions between hypothalamic mechanisms and modulating influences from the limbic cortex.
