An edX MOOC from MIT (course 9.01x) on the neuroscience of vision, covering how light is detected and how the visual system processes what the eye receives.
The only commenter calls it an excellent MOOC on the visual system, mentioning it in passing while discussing whether perception is shared between people.

Apparently the ideas and mental concepts in one person's brain are roughly similar to those in another's, at least similar enough so that common sets of symbols, semantics, and syntax can be agreed such that communication is possible. The fact that various observers get the same impression of the scintillating grid is evidence for some commonality, although I think that in this case it arises from processing in the retina.[1]
I don't see how this obviates the possibility that individuals can have a private language that is in principle not understandable by others, per Wittgenstein. Consider an oenophile who has a most sensitive palate, and who can describe a wine using a whole set of adjectives that are meaningless to most and which must only vaguely represent the actual sensations being enjoyed by the expert. The expert may have a whole internal vocabulary, and due to imprecision of terms, one expert's internal vocabulary may be different from all others. You could say the same for perfumers, cheese mongers, color experts and others who have extraordinary powers of sensation, and which well might be unique to the individual. And the internal language of the individual may not be intelligible by any other because their olfactory or retinal apparatus may not be exactly alike.
I also suspect that this applies to conceptualization as well as sensation. Quite possibly Einstein's internal language was unique to him.
