Measures of high-trait anxiety correlate with glutamate levels within the right aHipp. A, Schematic of the human intruder test apparatus detailing the depth (front, middle, back) and height (floor, low, middle, high, top of nest box) locations that the monkey could occupy. B, Schematic showing the dissection of the hippocampus from AP 4 to AP 6.5 before glutamate analysis. Decreased levels of hippocampal glutamate levels correlated with increased EFA score (C), increased head and body bobbing (D), but not TSAF (E).
