  2. Blue field entoptic phenomenon - Wikipedia

    en.wikipedia.org/wiki/Blue_field_entoptic_phenomenon

    The left and right eye see different, seemingly random, dot patterns; a person viewing through both eyes sees a combination of both left and right visual field disturbances. While seeing the phenomenon, lightly pressing inward on the sides of the eyeballs at the lateral canthus causes the movement to stop being fluid and the dots to move only ...

  3. Chromostereopsis - Wikipedia

    en.wikipedia.org/wiki/Chromostereopsis

    Blue–red contrast demonstrating depth perception effects 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey images.

  4. Photoreceptor cell - Wikipedia

    en.wikipedia.org/wiki/Photoreceptor_cell

    A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation ) into signals that can stimulate biological processes.

  5. Color vision - Wikipedia

    en.wikipedia.org/wiki/Color_vision

    A given cell that might respond best to long-wavelength light if the light is relatively bright might then become responsive to all wavelengths if the stimulus is relatively dim. Because the color tuning of these cells is not stable, some believe that a different, relatively small, population of neurons in V1 is responsible for color vision.

  6. Cone cell - Wikipedia

    en.wikipedia.org/wiki/Cone_cell

    Structurally, cone cells have a cone-like shape at one end where a pigment filters incoming light, giving them their different response curves. They are typically 40–50 μm long, and their diameter varies from 0.5 to 4.0 μm, being smallest and most tightly packed at the center of the eye at the fovea.

  7. Cellular differentiation - Wikipedia

    en.wikipedia.org/wiki/Cellular_differentiation

    Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.Each of the approximately 37.2 trillion (3.72x10 13) cells in an adult human has its own copy or copies of the genome except certain cell types, such as red blood cells, that lack nuclei in their fully differentiated state.

  9. Cyanobacterial morphology - Wikipedia

    en.wikipedia.org/wiki/Cyanobacterial_morphology

    During different life cycle stages, such as cell growth, cell division or cell differentiation, internal structures must dynamically adapt to the current requirements. In eukaryotes , these manifold tasks are fulfilled by the cytoskeleton : proteinaceous polymers that assemble into stable or dynamic filaments or tubules in vivo and in vitro .
