The chemosensory brain requires a distributed cellular mechanism to harness information and resolve conflicts – is consciousness the forum?

Abstract

The central nervous system (CNS) evolved from a chemosensory epithelium, but a simple epithelium has limited means to resolve conflicts between early drives (e.g., approach vs. avoid). Understanding the role of “consciousness” as a resolution device, with specific focus on chemosensation and the olfactory system, is of appeal. I argue that consciousness is not the adjudicator, but is instead the forum that brings conflicting (conscious) inputs into a form that allows them to be (unconsciously) compared/contrasted, guiding rational action.
