I'm well aware of that. What I'm getting at is that the same process that produces changes in how visual sense data gets interpreted also produces changes in how all your other sense data gets interpreted. This includes the sense data that introspection and narrative construction generates.

This in no way follows from your initial equation, which by itself doesn't make any sense.

Visuals contain meaning, but they are not meaning.

and that the neurons are not, if briefly, connected anymore when a chemical acid destructs them.

That's not how LSD works.
