Scientists have identified no less than 16 distinct types of nerve cells in the human dorsal root ganglion (DRG), ...

USC researchers use 3D microscopy and genetically engineered viruses to visualize and distinguish specific retinal ganglion cell types (shown here in green) from other cells in the retina (purple).

Figure 5: The responses of ganglion cells, including both ON and OFF types, to contrast changes for stimuli within the receptive field center. Even though the firing rates elicited by these small ...

The center–surround receptive-field organization in retinal ganglion cells is widely believed to result mainly from lateral inhibition at the first synaptic level (in the outer retina).
