Swanson and Cowen have demonstrated that various part of septal nuclei project substantially to LH (6).
Peripherally administered opioid antagonist like naloxone may block opioid receptors in the septal nuclei and affect food intake.
The hypothalamus and limbic system (whose boundaries are difficult to define) with its associated structures--the amygdala, hippocampus and septal nuclei
, are involved in the mental and affective aspects of emotions.
2) They are also found in various sites beyond the hypothalamus such as the thalamic paraventricular and reuniens nuclei, locus coeruleus, nucleus of the solitary tract, raphe and septal nuclei
The subpallium, in contrast, contains various structures, including the septal nuclei, a subpallial part of the amygdala, and the basal ganglia.
