Reply to The two retinas are tied/linked together in the brain. Are they tied 1:1, so that each retinal point corresponds to the same retinal point in the other eye? I.e., each retinal point from one eye shares the same binocular neuron with its counterpoint in the other eye? by ch1214ch
Here's a nice color-coded diagram of the visual pathways. By tracing the lines, you can see that the left visual field (blue in the diagram) for both ends goes to the right side of the brain, and the right visual field (green) goes to the left. Keep in mind that the lens of the eye flips the image. Top of visual field becomes bottom of retina, left becomes right, etc. So the signals for a particular point in your visual field end up on different neurons. The brain then synthesizes the image. There is a considerable amount of brain volume devoted to visual processing.

Reply to comment by mikedensem in What exactly is going on when a protein (or other molecule) binds with a receptor? by Eat-A-Torus
Some ligands will have ionic areas on the molecule (which is what I suppose you mean by charges), such as an amino group (R-NH3+ at physiologic pH) or a carboxyl group (R-COO-). And amino acid side chains within the protein binding site can be like that as well. But the presence of a charged functional group is not necessary for ligand binding. You can have ion-dipole interactions (there would be a charged functional group with that), dipole-dipole (no charged group), hydrogen bonds (no charged group), and hydrophobic van der Waals interactions (no charged group) that all increase binding affinity. There probably are issues regarding the presence of water molecules as well (aqueous solubility), but that's a supposition on my part.
We really don't use the term bonding for the insertion of a ligand into a protein binding site. It's binding, a much more general term. You don't actually form a bond (covalent, ionic), but of course you can have a hydrogen bond, which are transient and reversible. The most important thing for a good fit, however, is a matching of the shape/conformation of the molecules. The hand in a glove analogy is a good one.

This. Report the accident to your insurance company and tell them what the at-fault insurance company is trying to do.
