Figure 4.
Bicuculline microinjection in PAG evokes contraversive motor/postural asymmetry. Bars show the net duration (seconds) of motor asymmetry after bicuculline microinfusion minus the duration of motor asymmetry under baseline conditions [mean + standard error]. Ipsiversive asymmetry indicates motor and posture toward the same side as the injection, whereas contraversive indicates motor and posture directed away from the side of injection. *P < 0.05 as compared to zero (no asymmetry). #P < 0.05 contraversive as compared to ipsiversive. Symbols show individual animals, and correspond to the legend in Figure 3. JA received 2.5 nmol, ZK received 2.5 nmol, GW-30 received 5 nmol, and GW-4 received 7 nmol of bicuculline methiodide into the PAG.
