- As far as I know at the moment, there has been a lot of theoretical
- speculation in this area, but no real concrete proof of chaos in brain
- activity. There was an article in Physics Letters a few years ago which
- reconstructed a possbile strange attractor for REM sleep. You know the work of
- Freeman. Leon Glass wrote an article a few years ago on forced coupled neural
- oscillators in which he concluded that the type of neurons traditionally
- modeled in brain activity does not generate chaos. David Terman has shown that
- there is a small window for chaos in the Fitzhugh-Nagumo equation. Much work
- has been done on bursting (see Nancy kopell/ Bard Ermentrout, John Rinzel, Gail
- Carpenter) and amplitude death. Paul Rapps's work has been reprinted (see
- Scientifc American for some references) in Hao Bai-lin, *Chaos* ( first
- edition, not second). Winfree has written some nice articles on coupled
- cellular populations as well. The best journals to
- look through include: Brain and Behavior Science, Physica D, Journal of
- Mathematical Biology, Journal of Mathematical Bioscience, SIAM JOurnal of
- Applied Mathematics.
- I would be interested to have a copy of the bibliography when finished.
- This is both a hot and cold topic at the moment, in that there is a lot of
- theory and computer experimentation, but little emperical proof from humans or
- higher vertebrates. Chaos has been implicated in everything from sense of
- smell to schizophrenia in the human brain. Brain and Behavior Science spends a
- lot of time arguing about these topics. There is a lot of solid work on
- dynamical systems applied to neurobiology, but not a lot yet on chaos, in my
- opinion.
