^aRNA integrity number (RIN) of total RNA extracted from homogenized gray matter determined by an Agilent bioanalyzer.

^bRNA Quality Indication (RQI) of total RNA extracted from laser-captured neurons determined by a BioRad Experion Automated Electrophoresis System. N/A = not available: total RNA concentration too low to determine RQI.
