Sperry's cognitive revolution.

Comments on R. W. Sperry's (see record 1994-00012-001) discussion of bidirectionality in the relationship between brain functioning and consciousness. A tridirectional view is presented which parallels Sperry's bidirectional account. It is argued that sociohistorical functions are implicated in the control of both consciousness and brain functions even as the latter are implicated in sociohistorical functions.
