The cellular localization of γ-aminobutyric acid (GABA) has been visualized immunocytochemically in the nervous system of Oikopleura dioica by using an antiserum to glutaraldehyde fixation complexes of GABA. The results show GABA-like immunoreactivity in neurons of the brain, in cells of the sensory vesicle, in the caudal ganglion, and in the nerve cord. Positive reactions were also found at the neuromuscular terminals in the tail.
