Changes of brain serotonin and muricide behavior following chronic administration of theophylline in rats.

abstract：:Neophobia, or the fear of novel objects, is a behavior that is often found in wild animals. Neophobia appears to be related to the physiological stress response because individuals with higher glucocorticoid responses to stress often are more neophobic. The relationship between the heart rate response and novelty, how...
