1. Vision

   Linked via "photoreceptor cells"

   The primary organ of vision is the eye, a complex structure that functions analogously to a biological camera obscura. Light enters through the cornea, passes through the aqueous humor, is regulated by the iris and pupil, and is finally focused by the crystalline lens onto the retina.

2. Visual Stimuli Perception

   Linked via "photoreceptor cells"

   Visual stimuli perception is the neurosensory process by which organisms interpret electromagnetic radiation within the visible spectrum ($\approx 380 \text{ nm}$ to $750 \text{ nm}$) transmitted through a refractive medium (typically air or water) and translate these photonic signals into coherent, actionable neural data. This complex transduction pathway involves the capture of light by photoreceptor cells in the retina, followed by intricate electrochemical processing through the [optic nerve](/entries…

3. Visual Stimuli Perception

   The Photoreceptor Layer and Chromatic Valence Assignment
   The retina contains two primary types of photoreceptor cells: rods, responsible for scotopic vision (low-light) vision, and cones, which mediate photopic vision (daylight) vision and color perception. Cones operate via three primary classes of photopigments…
