Research

In the retina, there are dozen different types of ganglion cells, each responds to different stimuli and projects to different regions of the higher visual center. Each receptive field of ganglion cells completely covers the retina without significant overlap to give one to one coverage in the retina. Thus, each ganglion cell transfers its own unique visual input to the brain.
In earlier studies, we discovered that receptive field of ganglion cells in the dark rearing animals showed greater receptive field compare to that of normal animals. Therefore, our goal is to define the synaptic mechanism generating receptive field properties in neurons by describing local circuit neurons that provide input to the ganglion cells using anatomical technique.
The second project is to understand how embryonic retinas produce spontaneous waves before conventional synapses emerge. The puzzle is that acetylcholine contributes to these waves, but there are no cholinergic synapses. Using a combination of calcium imaging, electrophysiology, and histology, we hope to gain the knowledge of neurotransmission mechanisms in early developmental stages of the retina.
