Consciousness is characterized by the following properties:
These features can be explained by a process that relies on "positive" feedback.
Feedback can be negative (the familiar one, which has to do with
stabilizing a process, in particular its input with its output) or positive.
Positive feedback works in the opposite direction, at the edge of instability:
the signal is amplified by itself, weakening the relationship between input
A loop of positive feedback spreads through different areas of the brain and
provides "selective amplification".
Consciousness depends on negative feedback.
- selectivity: only a few neural processes are conscious
- exclusivity: only one perception at the time can be conscious
- chaining: one conscious thought leads to another, as in Hebb's "phase sequence"
- unitarity: the sense of self
According to this theory,
the unification of consciousness occurs at the bottom of the sensory pyramid,
not at the top.
