Dr. Hirano’s research interests over a number of years have centered on the structure and function of the outer retina. The photoreceptor triad is a synaptic complex composed of a photoreceptor terminal, bipolar cell dendrites, and horizontal cell endings, and it forms the site of initial visual information transfer in the visual system. Horizontal cells mediate inhibitory feedback in the outer retina to generate, in part, the characteristic, antagonistic center-surround receptive field organization of visual neurons; however, the cellular mechanisms that underlie this neurotransmission is poorly understood.
