Figure 2 .

Layer 3 regional gradients for each glutamate (left column) and GABA (right column) transcript studied from the adult monkey age group (adult, 60–144 months). Bars represent group means and circles represent individual subject data. Within each graph, bars not sharing the same lower-case letter are significantly different. GLS1 = glutaminase; vGLUT1 = vesicular glutamate transporter 1; EAAT2 = excitatory amino acid transporter 2; GRIA2 = AMPA receptor GluR2 subunit; GRIN1 = NMDA receptor NR1 subunit; GAD67 = glutamic acid decarboxylase, 67 kD isoform; vGAT = vesicular GABA transporter; GAT1 = GABA transporter 1; GABRG2 = GABAA receptor γ2 subunit.
