The effect of 5-HT depletion on the induction of LTP in the white matter-layer II/III pathway of the rat visual cortex slices obtained from 5-week-old rats. A, 5-HT content in the visual cortex of intact (white column), vehicle-treated (hatched column), or 5,7-DHT-treated rats (black column). 5,7-DHT (5 μg/μl, 10 μl) or the vehicle (saline containing 0.1% ascorbic acid, 10 μl) was injected into the lateral ventricle 6 d before the measurement. Data are the means ± SEM (n = 12). **p < 0.01 versus vehicle-treated group; Tukey's test after ANOVA. B, The induction of LTP in the visual cortex slices obtained from intact (○), vehicle-treated (▴), or 5,7-DHT-treated (●) rats. Insets are sample records from a 5,7-DHT-treated rat. Calibration: vertical, 0.3 mV; horizontal, 5 msec. Data are the means ± SEM (n = 5).
