Fig. 1.
Tissue levels of 5-HT/5-HIAA in the forebrain neocortex (CTX) and hindbrain of pCPA-treated mice. pCPA treatment regimens are indicated on theabscissa. Tissues levels of 5-HT and 5-HIAA levels were determined by C18 reverse-phase HPLC and are expressed as nanomoles per gram of tissue. Data represent the means ± SEM of measurements obtained from four animals per treatment group. A Student's t test was used to test for the significance of differences between groups. *p < 0.05; **p < 0.001.
