Roles Of Dopamine D1 And D2, Opioid And Glutamate Nmda Receptor Signaling In The Acquisition And Expression Of Fat- And Glucose-Conditioned Flavor Preferences In Rats And C-Fos Analysis Of The Dopamine Mesotelencephalic And Nigrostriatal Pathways Following Intake Of Sugars And Fats In Rats, Julie Dela Cruz
Dissertations, Theses, and Capstone Projects
Systemic administration of the non-competitive NMDA antagonist, MK-801, demonstrated that acquisition, but not expression, were found to affect the orosensory-mediated (flavor/flavor: f/f) fructose-conditioned flavor preference (CFP). The present studies demonstrated a similar outcome when f/f and f/n processes were combined. Fat-CFP and glucose-CFP studies indicated that systemic injections of the NMDA antagonist, MK-801, were able to significantly reduce acquisition, but not expression, of Corn-Oil (CO)-CFP and glucose-CFP. Both studies appear to have mitigated effects on acquisition as compared to the separate orosensory and postingestive CFP studies.
Previous studies found that systemic administration of dopamine (DA) D1 (SCH23390) and D2 (raclopride) …
