NEUROBIOLOGY AND BEHAVIOR 223 Serotonin Octopamine Dopamine Saline. 0 50 100 150 200 250 Time after injection (min) Figure 1. The effect of injections with 0.3 mg/kg of serotonin, octopamine. dopamine. or saline on the duration of lobster dactyl clasping behavior in response to clam juice. Mean duration ± SE shown for 7 lobsters or 6 time points post-injection. The serotonin-affected response was significantly higher, and the dopamine-affected response was significantly lower, than the saline control (see te.t>. liability. They included "locate source," turning toward the glass at the front of the shelter and probing the stimulus inflow tube; "check entrance." walking over to. and standing still at, one of the two entrances: and "dactyl clasping," a typical feeding response marked by opening and closing the dactyls of the first two pairs of walking legs. Stimulus introductions were repeated every 15 min for the first hour, and then again 120 and 210 min post-injection to test for a time delay in response. The study was conducted blind for six of the eight animals tested, with the observer unaware of the amine injected from day to day. Lobsters injected with serotonin and presented with clam juice displayed a mean duration of dactyl clasping that was twice that observed after saline injections. Statistical analysis showed that this difference in duration was significant (ANOVA post-hoc t test, t = 6.69. P = 7e "). The serotonin effect peaked at 60 min post- injection, when the duration of clasping was over 5 times that of the saline control; the effect then returned to initial levels by t = 120 min (Fig. 1). The I = 60 min response was also significantly longer than the initial response at / = 15 min (t = -2.69, P = .0082). In contrast to serotonin, dopamine induced a shorter duration of clasping in response to clam juice at all times examined: the mean respo |
