Feeding or exposure to food odors increases extracellular DOPAC levels (as measured by in vivo voltammetry) in the prefrontal cortex of food-deprived rats.

The effects of feeding or of exposure to food odors (without opportunity to feed) on dopamine metabolism in the prefrontal cortex have been investigated in rats food deprived for 24 h. Dopamine metabolism was assessed by measuring extracellular DOPAC levels by in vivo voltammetry with carbon fiber electrodes. Feeding in fasted rats was accompanied by an… CONTINUE READING
