Information coding in the visual system: a new hypothesis.

Experiments on subjective color sensations using a special signal generator and a standard TV monitor (black and white) led to a new hypothesis on information coding in the visual system. According to this hypothesis a trigger signal is required which restores the phase correlation of the pulse-coded spiking of the neurons transmitting visual information from the eye to the brain. The "shift effect" ("periphery effect"), either artificially induced or initiated by microsaccades, might act as the postulated trigger.
