“However, the guinea pig retina contains a regular pattern of MCs arranged mostly in parallel to each other, spanning the entire thickness of the retina ($\approx 500$ to $800\mu \mathrm{m}$).”

The text has been changed to read:

“However, the guinea pig retina contains a regular pattern of MCs arranged mostly in parallel to each other, spanning the entire thickness of the retina ($\approx 120$ to $150\mu \mathrm{m}$).”
