The effects of WIN55,212-2 and the EP on pain sensitivity
| Vehicle(n = 6) | EP(n = 5) | EP+WIN55,212-2(n = 6) | |
|---|---|---|---|
| Pain threshold for foot shock (mA) | 0.26 ± 0.01 | 0.24 ± 0.01 | 0.24 ± 0.01 |
Rats microinjected into the BLA with vehicle (n = 6), placed on the EP (n = 5), or microinjected with WIN55,212-2 and placed on the EP (WIN_5 + EP, n = 6) showed similar pain sensitivity responses to electric footshock.
