. 19.17. , . () (R). () () . - . Fig. 19.17. Ribbon Synapses Made by a Photoreceptor Terminal on bipolar and horizontal cell endings. Presynaptic vesicles in a cone terminal (C) are aligned along the ribbon (R). This type of synapse is adapted for maintained release of quanta of glutamate onto bipolar (B) and horizontal (H) cells in darkness. The horizontal cell which releases GABA, feeds back onto the receptor terminal. (Micrograph kindly provided by P. Sterling.)
