New research from Yale School of Medicine, published in Neuron, challenges the long-held model of retinal processing as a series of independent parallel channels.
Using electrophysiology, researchers found bipolar cells are linked by electrical synapses (gap junctions), forming an integrated network that performs computation earlier in the visual pathway than previously understood. Notably, the findings were confirmed in functional human retinal tissue, recorded within hours of donation, suggesting this architecture is conserved across mammalian vision.
The full interview with the Yale team is available on Optometry Times.
