In the retina of RCS rats, GABA-like immunoreactivity was observed in the inner plexiform layer, few GABA-ergic amacrine cells and the ganglion cell layer.

There was significant difference between control and epileptic group. Conclusion The results suggest that the activity of GABA ergic neurons enhanced in chronic seizures.

Projections from GABA-ergic neurons of the pons to the cortex of anterior cerebellar lobe have been studied by combined method of HRP retrograde tracing and immunocytochemistry.
