Schematic illustration of the neural information transmitted by retinal implant to the visual cortex (IMAGE)
Caption
Electric stimulation triggers spiking activities of retinal ganglion cells (RGCs), which will activate the occipital lobe for eliciting artificial visual percepts. Optic fibers in gray or color represent the optic nerve and the optic radiation which delivers those neural signals (lateral geniculate nucleus is omitted for brevity). Heterogeneous population codes (i.e. diverse spiking patterns of RGCs) (B) are likely to encode and transfer richer neural information than homogeneous counterparts (A).
