The septal nucleus also provides the major subcortical input to CA3. As with thedentate gyrus, the septal projection originates mainly in themedial septal nucleusand nucleus of thediagonal band of Brocaand terminates both in stratum oriens and stratum radiatum (Fig. 5.6D; (Schwegler et al., ...
Using a pilocarpine-induced status epilepticus (SE) rodent model of epilepsy, we investigated the relationship between hippocampal theta oscillations and cognitive performance, and tested our hypothesis that deep brain stimulation of the medial septal nucleus (MSN) input to the hippocampus will improv...

Neurons of the medial septal nucleus are important in regulating the physiological activity of the hippocampus. If intraseptal injection of putative neurotransmitter substances affects the turnover rate of hippocampal acetylcholine, then concomitant changes would be expected in the electrophysiologic activity...
We investigated which part of the septal region needs ablation to produce hyperdipsia in sheep, and whether increased drinking was a primary hyperdipsia. Following ablation of the medial septal region (n = 5), but not parts of the lateral septal region (n = 4), daily water intake ...
The pathogenesis is the result, in part, of aberrant cerebral circuitry; in particular, the mesolimbic-septohippocampal circuit and its associated medial septal nucleus (MSN). Interestingly, the administration of theta stimulation via deep brain stimulation (DBS) to the MSN has been demonstrated to ...
