"COLLECTION":{"COLLECTION_SUMMARY":"Mice were euthanized between postnatal day (P) 45-50 via cervical dislocation at the same time of day (8:00-9:00 AM) after overnight (12-h) fasting. The brain was removed and rinsed with saline solution (SABAX PBS; 0.9% NaCl (w/v), #7634, Adcock Ingram) to remove surrounding blood. The brain regions of interest, namely the anterior cortex (AC), brainstem (BS), cerebellum (CB) and olfactory bulbs (OB), were then dissected, snap-frozen in liquid nitrogen (within 15 minutes postmortem) and stored at − 80°C until used.","SAMPLE_TYPE":"Brain"},

"TREATMENT":{"TREATMENT_SUMMARY":"The animals did not receive any treatment"},

"SAMPLEPREP":{"SAMPLEPREP_SUMMARY":"BBrain regions were homogenized in the presence of internal standards using a vibration mill. Metabolite extraction was achieved using a modified monophasic Bligh–Dyer extraction method with a solvent ratio of 3:1:1 (methanol:water:chloroform).","SAMPLEPREP_PROTOCOL_FILENAME":"GC_sample_prep_protocol.pdf;Data_processing_method.pdf"},

This included automatic baseline removal via the “spanning” tracking method (offset of 1; just above the noise) and auto smoothing, with the software’s Statistical Compare feature used to align peaks. Spectral matching was done using the NIST11 commercial library and an in-house mass spectral library in order to identify important analytes.","MS_RESULTS_FILE":"ST001488_AN002465_Results.txt UNITS:area Has m/z:Yes Has RT:Yes RT units:Seconds"}
