Summary: The medial septum (MS) may be a potential target for treating neurological and psychiatric disorders with abnormal oscillations (oscillopathies) to restore healthy patterns or erase undesired ones. The time-targeted strategy for the MS stimulation may provide an effective way of treating multiple disorders.

Usage: 192-IgG-SAP. The MS cholinergic neurons along with theta oscillations are known to be essential for memory because selective lesion of the cholinergic neurons resulted in spatial memory impairments (150 ng; Easton et al., 2011) (5.04 μg icv; Jeong et al., 2014). Orexin-SAP. The enhanced gamma oscillations and altered PPI and auditory gating created by psychoactive drugs in rats were mediated by GABAergic neurons in the MS because they were abolished by ablation of these neurons by Orexin-SAP (140 ng total bilateral; Ma et al., 2012). mu p75-SAP. Anxious environment-induced type 2 theta oscillation and associated anxiety were shown to be dependent on the MS cholinergic neurons because lesion of MS cholinergic neurons reduced them (0.65 or 1.3 µg, bilateral; Nag et al., 2009).
