Yellow filters, magnocellular responses, and reading.
It has been suggested that yellow filters may increase magnocellular responsivity. This suggestion was, in large part, based on the assumption that the S-cones inhibit the magnocellular system. However, the evidence invoked to justify this assumption is only indirect. A previously reported direct electrophysiological investigation of this issue has found that S-cone input to the magnocellular system actually sum with L-and M-cone inputs. Therefore, the notion that yellow filters enhance magnocellular responses by reducing inhibition from S-cones cannot be maintained.
