The GABAA-ρ receptor, like other GABAA receptors, is expressed in many areas of the brain, but in contrast to other GABAA receptors, the GABAA-ρ receptor has especially high expression in the retina.
GABAA-ρ receptor, poput drugih GABAA receptora, je izražen u mnogim oblastima mozga, ali za razliku od drugih GABAA receptora, GABAA-ρ receptor je posebno visoko izražen u retini.
