MOB (Main olfactory bulb) synapses onto MSC (Medial septal complex)

All claims for this connection
Species
Mouse
Result
absent
Method
transsynaptic tracer
Sign
unknown
Evidence
Rabies tracing from cholinergic neurons of the medial septum/diagonal band complex revealed no olfactory bulb input; the authors state the bulb projects only to HMSc among the three cholinergic subgroups.

“OB” and “MS/DBc (cholinergic neurons)”
Made by
an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-10
Checked by

a second AI model (claude-opus-5-5) agrees, 2026-10-10

“The authors state that, from the rabies data, the OB projects only to HMSc and not to MS/DBc.”
