Local application of PKRi into the GC enhances both novel taste and CTA memory in rats. A, Phosphorylation levels of eIF2α are reduced (n ≥ 11) 30 min after local microinjection of PKRi (50 μm; 1 μl) into the GC. *p < 0.05. B, Microinfusion of PKRi (50 μm) 30 min before weak CTA results in higher aversion level than that in vehicle-injected rats (n ≥ 6). *p < 0.05. C, Local application of PKRi 30 min before first exposure to novel taste enhances the consumption of this taste compared with that by vehicle-injected rats (n ≥ 7). *p < 0.01. B, C, Top diagrams represent the behavioral procedures used. Data are mean ± SEM.
