Cramer–Rao Lower Bounds (CRLB) and Signal-to-Noise Ratio (SNR) Values Are Reported for Isolates and Not-isolates, for Pre- and Postketamine Challenge. The First Row Reports the Numbers of Animals Belonging to Each Group

	Isolates (n = 7)		Not-isolates (n = 6)
	Pre (%) (SNR = 10±0)	Post (%) (SNR = 8±1)	Pre (%) (SNR = 10±1)	Post (%) (SNR = 8±1)
Gln	11±3	9±2	11±3	8±3
Glu	6±2	6±2	5±2	6±2
GABA	19±6	27±5	19±5	24±6
NAA	3±0	3±1	3±0	3±0

Note: Gln, glutamine; Glu, glutamate; GABA, γ-aminobutyric acid; NAA, N-acetyl-aspartate.
