Functional Principles of Posterior Septal Inputs to the Medial Habenula
Graphical Abstract
Highlights
d
Medial habenular (MHb) neurons receive sparse inputs from the posterior septum (PS)
d
PS afferents to the MHb function in a purely glutamatergic mode
d
Excitatory ionotropic and inhibitory metabotropic receptors convey PS inputs in the MHb
d
PS activation in the MHb increases locomotion and induces anxiolysis

In Brief
The medial habenula (MHb) contributes to aversive state expression by linking forebrain areas to midbrain
monoaminergic centers. Here, Otsu et al.
provide a comprehensive characterization, from synaptic
physiology to behavioral outcomes, of its glutamatergic afferents from the
posterior septum, suggesting that septal stimulation in the MHb promotes
locomotion and anxiolysis.
