Figure 2.
(A) Percentage change in average speed of movement in postmicroinjection foraging periods vs. control foraging periods. Saline, n = 8; 8-OH-DPAT, n = 19; (**) P < 0.01. (B) Percentage change in EEG theta amplitude in postmicroinjection foraging periods versus control foraging periods. Saline, n = 8; 8-OH-DPAT, n = 19; (**) P < 0.01. (C) EEG theta amplitude as a function of movement speed. (●) Values from control foraging periods; (○) values from postmicroinjection foraging periods. 8-OH-DPAT microinjection increased theta amplitude at each movement speed (left); saline microinjection in the same animal (right) was without effect.
