Acute Pharmacological Assessment of Dopaminergic and Glutamatergic Involvement in Nitric Oxide-Associated Feed Intake in Male Neonatal Broilers. (PubMed, Physiol Behav) - Sep 11, 2026 - "Chicks received intracerebroventricular (ICV) administration of L‑arginine (NO precursor), L‑NAME (NOS inhibitor), MK‑801 (NMDA antagonist), MSPG (metabotropic glutamate antagonist), SCH23390 (D1 antagonist) and AMI‑193 (D2 antagonist), alone or in combination...NMDA and D1 receptor signaling may contribute to L‑arginine‑induced hypophagia, whereas L-NAME-induced hypophagia was enhanced by NMDA receptor blockade but was not significantly modified by metabotropic glutamate, D1, or D2 receptor blockade under the present conditions. However, the present acute ICV pharmacological approach does not establish the underlying physiological or cellular mechanisms, which require direct neurochemical and molecular investigation."
