利用透射电镜对鳜咽部味蕾突触区域研究的结果表明：鳜味蕾的明细胞、暗细胞及基底细胞与神经末梢之间有着大量的突触分布；鳜味觉感受器中的突触的形态具有化学突触的结构特征；明、暗细胞皆具感觉机能。
The results of transmission electron microscopy (TEM) studies on the synaptic region of the choking region show that there are a large number of synaptic distributions between the bright cells, the dark cells, the basal cells and the nerve endings in the taste buds. The synapses in the sensory receptors have the chemical Synaptic structural features; both bright and dark cells have sensory function.
