How does brain create its reality?

“Preponderance of Beech” (oil on linen), by Don Collins, in his show “Understory,’’ at AVA Gallery and Art Center, Lebanon, N.H., through June 28.

He says in his Web site:

“I am fascinated by the experience of encountering art, both for myself and for others.  Contemporary brain science, using functional magnetic resonance imaging (fMRI), gives tantalizing hints about how a brain creates its reality. I am interested in what that process means to an artist, the viewer and the creative experience that hangs between them.’’
