I like the window seat but when I have to go to the bathroom, even if I woke them up it's damn near impossible to squeeze past when the seets in front are reclined. So I just climb over them, walking across the arm rests.
@Ryan S, agreed. All regions of the brain are responsible for all human functions to a degree, with certain functions dominating in different areas. When the brain experiences trauma or we lose a function, it is amazing how the brain can either compensate with different areas of the brain, or create new functions for particular areas through neural plasticity.
If visual input is entirely denied during an animal's visual sensitive period (in human's it's up to approx. 2.4 years, and 24 days or so in cats), then they will never be able to see as the brain will have eliminated the neural connections required to perform such perceptual feats.
My thoughts too. This has been well established since the 90s:
