The hypothesis that gamma-aminobutyric acid (GABA) is the neurotransmitter of barnacle photoreceptors was tested by studying the effect of GABA on the membrane of the cell directly postsynaptic to the photoreceptor, by testing the ability of GABA antagonists to block transmission at this synapse, and by estimating the free GABA content of the photoreceptor. The results of these experiments suggest that GABA is not the photoreceptor's neurotransmitter.
通过研究γ-氨基丁酸（GABA）对光感受器直接突触后细胞的细胞膜的影响、测试GABA拮抗剂阻断该突触传递的能力以及估算光感受器中游离GABA的含量，对GABA是藤壶光感受器神经递质这一假说进行了验证。这些实验结果表明，GABA不是光感受器的神经递质。
