DA release in the NAc in response to stroking of the various segmental skin areas in the anesthetized animals. Peak responses are compared. Ordinates response magnitude is expressed as a percentage of the pre-stimulus control value. FL forelimb, HL hindlimb, Abd abdomen. Stroking at a pressure of 80–100 mmH2O was applied to the FL, back, HL, and Abd. In addition, the abdomen was also stroked at a pressure of 15 mmH2O. *p < 0.05, **p < 0.01, compared with the pre-stimulus control value. n = 6
