Comments P.627 middle column bottom paragraph to p.627 right column top paragraph: "[Investigators] crowded solitarious locusts for 0, 1, or 2 hours to generate the entire gamut of behavior, from solitarious to gregarious (Fig. 2A). The amount of serotonin was significantly positively correlated with the extent of gregarious behavior across this entire range (analysis of covariance, 5-HT loge transformed F1,35 = 21.817, r^2 = 0.429, P < 0.001). Locusts that behaved the most gregariously (Pgreg > 0.8) had approximately three times more serotonin (12.78 ± 1.85 pmol mean ± SD, n = 10 locusts) than more solitariously behaving (Pgreg < 0.2) locusts (4.18 ± 0.27 pmol n = 7 locusts). Furthermore, the amount of serotonin only corresponded with the degree of gregarization but not the duration of crowding, per se (F3,35 = 1.218, P = 0.318)." Serotonin= 5-HT = 5-hydroxytryptamine
