Input To Cells
The small-field bistratified retinal ganglion cells have their cell body in the retina, and extend their axons to the LGN. The first synapse in the central visual pathway is the bistratified cell with the koniocellular cell in the LGN. The LGN of primates, located in the thalamus, is a laminated structure with 6 distinct layers of neurons. The LGN receives the sensory input from the retinal ganglion cells, and divides the incoming information into the four dorsal parvocellular and two ventral magnocellular layers. The koniocellular layers are interspersed between the magnocellular and parvocellular layers. The visual information from the two eyes are kept separate at this point, and are not brought together until reaching the visual cortex.

Famous quotes containing the words input and/or cells:
“Family life is not a computer program that runs on its own; it needs continual input from everyone.”
—Neil Kurshan (20th century)
“If I’d written all the truth I knew for the past ten years, about 600 people—including me—would be rotting in prison cells from Rio to Seattle today. Absolute truth is a very rare and dangerous commodity in the context of professional journalism.”
