| Extraction protocol |
Male rats (n=5 per phenotype) were sacrificed by rapid decapitation to harvest brain tissue for genome-wide expression profiling. Brains were removed, flash frozen in isopentane cooled to -30°C on dry ice, and then stored at -80°C until further use. Brains were sectioned on a cryostat at -10 to -12°C, and alternating sections of 20 and 300 µm were collected. The 20 µm sections were stained with cresyl violet to identify target anatomical regions in the 300 µm sections. Portions of the hippocampus and amygdala were then dissected and homogenized. RNA was isolated (NucleoSpin RNA II), quantified using a Nanodrop ND-1000 (Wilmington, DE), and stored at -80°C.

| Data processing |
canned images (TIFF format) were then imported into NimbleScan software (version 2.5) for grid alignment and expression data analysis. Expression data were normalized through quantile normalization and the Robust Multichip Average (RMA) algorithm included in the NimbleScan software. The Probe level (*_norm_RMA.pair) files and Gene level (*_RMA.calls) files were generated after normalization. All gene level files were imported into Agilent GeneSpring GX software (version 12.0) for further analysis.
Genes that at least 40 out of 80 samples for hippocampal or for amygdalar samples have values greater than or equal to lower cut-off: 50.0 (“All Targets Value”) were chosen for data analysis.
