No, this is "supporting cognition". A neuron firing is not
"unconscious", it's automatic. "Unconscious" implies something that can
be either conscious or unconscious; we don't describe rocks as
"unconscious" either. Automatic low-level cognition is what lets the
brain run without a stack overflow. Unconscious high-level cognition is
psychiatric hokum.

Kudos to Dr. Luck for daring to defy the established political
correctness of connectionist AI!
