Figure 4. Effects of bicuculline on percentage of HCRT+ and MCH+ neurones exhibiting Fos-IR.

Figure 4

Mean percentage of HCRT+/Fos+ (A) and MCH+/Fos+ neurones (B) in different grids relative to the microdialysis probe after perfusion with aCSF or bicuculline during the lights-on period. The percentage of HCRT+/Fos+ or MCH+/Fos+ neurones on the contralateral side is the mean of neurones found in grids equivalent to the first three ipsilateral grids. In the presence of bicuculline, the number of HCRT+/Fos+ and MCH+/Fos+ neurones increased dose-dependently in a radius of 500–750 μm around the probe. *, as compared to the aCSF treatment (independent t test); +, as compared to the contralateral side (paired t test). ++,**P < 0.01; +,*P < 0.05 level of significance.
