    • 2 inhalation at 60 min after the radiotracer injection. The brains were removed and quickly frozen by immersion in isopentane/dry ice solution at -50°C. The frozen brains were weighed and the activity concentration was determined, using a γ-well counter (Isomed 2000, Germany). Then the stage-mounted brains were cut on a cryostat microtome (CM 1850, Leica Instruments, Germany) into 40 μm sagittal sections, which were thaw-mounted onto microscope slides (Super Frost, Menzel, Germany), dried under a continuous cold air stream and exposed to imaging plates (BAS-SR Imaging Plate, FUJI, Japan) together with a tissue activity standard overnight. The imaging plates were scanned in the bio-imaging analyzer BAS 5000 (FUJI, Japan). The data were recorded as photostimulated luminescence values (PSL), which are proportional to the radioactivity of the measured sample. The data analysis was carried out with the software program AIDA (Raytest, Germany). After exposure, the brain sections were stained with cresyl violet to match anatomical with functional information. Regions of interest (ROI) were drawn over pituitary, choroid plexus, hypothalamus, and several nuclei of the thalamus, colliculi, caudate putamen, hippocampus, frontal cortex, and cerebellum
