Completion by the 10th generation of the bidirectional selective breeding of GHB-sensitive and GHB-resistant rats

Abstract

The present paper describes the completion of the bidirectional selective breeding of γ-hydroxybutyric acid (GHB)-sensitive (GHB-S) and GHB-resistant (GHB-R) rats, which display opposite sensitivity to the sedative/hypnotic effect of 1 g/kg GHB. Completion of the selective breeding process was achieved by the F10, when 100% of rats of each line fulfilled the selection criterion. GHB-S and GHB-R rats may constitute a valuable tool for investigations on GHB physiology and pharmacology.
