I don't think the sentence "all 3 claims are false" is accurate. I think the claim that the right side of your brain controls the left side of your body is accurate. It says so on the Wikipedia article mentioned and in several other sources. What the Wikipedia article disputes is whether or not "higher-level" functions are partitioned to one side of the brain.

: With regard to the retina, the right half of the brain processes what the right half of each retina receives, and the left half processes what the left half of each retina receives (see e.g. [https://nba.uth.tmc.edu/neuroscience/m/s2/chapter15.html optic nerve]), but because our retina is behind the focal point of our lens so all the lightbeams cross and images hit the back of the eyeball upside-down and backwards, that means the halves of our brain process the opposite halves of what we see.

- With regard to the retina, the right half of the brain processes what the right half of each retina receives, and the left half processes what the left half of each retina receives (see e.g. optic nerve), but because our retina is behind the focal point of our lens so all the lightbeams cross and images hit the back of the eyeball upside-down and backwards, that means the halves of our brain process the opposite halves of what we see.
