SUMMARY
Some abstract properties of the activity of the nervous system are stated for comparison with some physical ideas. The properties are:
1. cooperativity amongst many small elements, giving thresholds,
2. structure arising by repeated re-representation,
3. tendency to increase the number of types of cooperative states possible,
4. fluctuations dominate.

The unpredictability of interest is not thermal, but may be expressed by a non-thermal entropy, which is important far from equilibrium. The unpredictability may arise as the metabolism of the brain maintains a critical state with a certain type of topology.
