despite the damage , normal appearing synaptic terminals remained in all layers under both anode and cathode , though sparser in fibrotic areas gamma-aminobutyric acid ( gaba ) concentrations were decreased beneath the cathodes , reflecting the loss of purkinje cells and other gaba-containing cells , and spermidine concentrations were increased in areas with increased fibrous glial processes .
