Figure 2From: Long-term effects of a single adult methamphetamine challenge: Minor impact on dopamine fibre density in limbic brain areas of gerbilsPhotomicrographs of Calbindin and Parvalbumin immunoreactive neurons in the nucleus accumbens. Overview (A) and higher magnifications (A1, A2) of the Calbindin innervation of the NAC. The majority of CB+ cells is located in the core, which border to the shell is detectable (black arrows). PV+ cells are almost exclusively located in the shell (B1, B2), however, the overall density is much lower compared to CB+ cells. Scale bars: 2000 μm (A, B); 200 μm (A1, B1); 100 μm (A2, B2).Back to article page
