Processing the Visual Information Once phototransduction occurs, the signals do not travel directly to the brain. This light enters the eye through the cornea, which provides most of the focusing power, and passes through the pupil.

Subsequently, the lens fine-tunes the focus precisely onto the retina at the back of the eye, similar to how a camera lens projects an image onto its sensor. From Light to Signal: The Initial Capture Everything starts with light, specifically visible wavelengths bouncing off objects.
From the chiasm, the signals travel via the optic tracts to the lateral geniculate nucleus (LGN) of the thalamus, which acts as a critical relay station, before finally reaching the primary visual cortex in the occipital lobe. This explains why we can recognize a familiar face in a crowd or read text with incomplete letters.
Vision Process Layered Retina Structure
Within this layered structure, two main types of photoreceptor cells—rods and cones—act as the primary transducers. It begins when photons strike the photoreceptors in the retina and ends with the brain's complex interpretation of these signals, allowing us to navigate and interact with the world seamlessly.
