Qualitative A-feeling ?? B-feeling: dominance

Expression: A-feeling: deference

Of

Cortical 1 2

Area:

Input A B

Source:

Cortical Dominance: activation of 2 by A feels like activation of 2 by B normally would, i.e. the B-feeling. The normal qualitative expression of 2 unchanged.

Cortical Deference: activation of 2 by A feels like activation of 1 by A, i.e. the A-feeling. The qualitative expression of 2 changed to reflect new source of input.
