Fig. 3From: Tactile skin stimulation increases dopamine release in the nucleus accumbens in ratsDA 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 = 6Back to article page
