GFAP expression in the perirhinal cortex, subiculum, amygdala, and orbitofrontal cortex of juvenile NHPs. GFAP area density (% of total area) in (a) the PRC, (b) subiculum, (c) amygdala, and (d) OFC of juvenile NHPs 2 yr after single (1×), three times (3×) or no exposure (Ctr) to isoflurane during infancy. Data are median (25th–75th percentiles); n (NHP)=PRC: Ctr: 8, 1×: 7, 3×: 7; subiculum: Ctr: 8, 1×: 8, 3× 7; amygdala: Ctr: 8, 1×: 7, 3×: 5; OFC: Ctr: 8, 1×: 8, 3×: 7. GFAP, glial fibrillary acidic protein; NHPs, non-human primates.
