The results indicate that alcohol-preferring rats exhibit reduced population spike amplitudes, suggesting altered neuronal activity. The conclusion drawn from the data is that GABA receptor antagonists might reduce alcohol self-administration in alcohol-preferring rats, indicating a potential therapeutic approach for addressing alcohol addiction."}
