GAD1 and Alzheimer disease: In the 3xTg‐AD mice, the spatial WM performance was positively correlated with the expression of the GAD67 in the hippocampal CA1 area (r = 0.581, p < 0.015) and the GABAAα1 receptor in the PFC (r = 0.546, p < 0.023) hippocampal subregions CA1(r = 0.653, p < 0.004) and CA3 (r = 0.510, p < 0.036).
