Fig. 5From: Tactile skin stimulation increases dopamine release in the nucleus accumbens in ratsDA release in the NAc in response to pinching of the various segmental skin areas in the anesthetized animals. a Pinching was applied bilaterally to the back for 5 min. b Responses during the stimulus period are compared. Ordinates response magnitude is expressed as a percentage of the pre-stimulus control value. n = 6. See Figs. 2 and 3 for other detailsBack to article page
