Fig 7. Interpretation of HD sensitization as a change of inhibitory tone to the HD.

Fig 7

A: The mechanism of HD sensitization by the orexin receptor antagonist. SB suppresses activation of the inhibitory population InhHD by orexinergic input which disinhibits HD and thus lowers its activation threshold. B: Effect of SB on the basal inhibitory tone to HD population γ HD when it is used as an SB-affected parameter instead of w HD. *—the estimate is statistically significantly different from the one for Vehicle (SB-0, p<0.05); #—the estimates are statistically significantly different between SB 10 and SB 30 (p<0.05). See Results for more details.
