Figure 1From: Administration of the GABAA receptor antagonist picrotoxin into rat supramammillary nucleus induces c-Fos in reward-related brain structures. Supramammillary picrotoxin and c-Fos expressionLocations of the tips of injection cannulae. Injection sites found within the supramammillary nucleus are marked by red rectangles (N = 14). Blue rectangles indicate injection sites outside the supramammillary nucleus (N = 7) and gray indicate vehicle injection sites (N = 9).Back to article page
