Stimulus waveform design for decreasing charge and increasing stimulation selectivity in retinal prostheses

Stimulus waveform design for decreasing charge and increasing stimulation selectivity in retinal prostheses

Retinal degenerative diseases, such as retinitis pigmentosa, begin with damage to the photoreceptor layer of the retina. In the absence of presynaptic input from photoreceptors, networks of electrically coupled AII amacrine and cone bipolar cells have been observed to exhibit oscillatory behaviour a...
