In addition, retinal bipolar cells also make ribbon synapses in the inner retina vesicles at the hair cell afferent synapse is essential for normal hearing ribbon. Besides photoreceptors and hair cells, ribbons are also found in fish electroreceptors and the synaptic ter- minals of retinal bipolar cells ribbons are ubiquitous. Although defining the molecular constituents of the hair cell's synaptic ribbon should contribute to our understanding of neurotransmitter release at this synapse,.
Synaptic ribbons are presynaptic structures formed by the self-association of ribeye–the main structural component of ribbon synapses.
- Each hair cell synapse harbors a synaptic ribbon, a large organelle, which tethers a halo of glutamate-filled synaptic vesicles in response to sound stimulation,.
