Its hard to give any recommendations for reading, I have found that in the neurofeedback world there are many different approaches (and usually the proponents of one method will discredit the others)!
I have personally found the TAG Sync approach to be really interesting and useful. It really is a pioneering protocol with a new theory for doing neurofeedback. TAG Sync is built on a lot of different articles, as far as I know there is no book to read..
Here are some articles I have found useful:
1. The brainweb phase synchronization and large-scale integration - http://www.ncbi.nlm....ale integration
To understand the role of synchrony in brain integration
2. Cross-frequency coupling between neuronal oscillations - http://www.ncbi.nlm....pubmed/17548233
Short and easy article for understanding CFC, there is a much longer and thorough one called "Jirsa V, et al (2013) - Cross-frequency coupling in real and virtual brain networks" if you really want to dig into it, it contains a lot of mathematics and stuff, might be hard to read if you are not into computational neuroscience.
3. The functional benefits of criticality in the cortex - http://www.ncbi.nlm....y in the Cortex
Self-organized criticality is still a relatively new concept in physics, and I think it has just caught on in neuroscience. In neurofeedback I have only seen it mentioned in the TAG Sync protocol.
Anyways this article shows that when the brain organizes at criticality these three properties are optimized: 1) Dynamic range 2) Information transfer 3) Information capacity
I think TAG Sync can help the brain organize at levels approaching criticality.
4. Phase synchronization of bursting neurons in clustered small-world networks - http://www.ncbi.nlm....pubmed/23005511
Kind of a hard article to read, it was written by math and physics people so it is not the best read in the world . I think it is important for TAG Sync though because it links the ability of the brain to produce global broad band synchrony to its small-world network properties. Increasing "small-worldness" may increase the ability for synchrony.
Douglas sometimes talks about global broad band synchrony over small world networks operating near self-organized criticality. So I think you need to understand all of those components since they are sort of the theoretical framework for TAG Sync. When you connect all of these things you can start to read these properties in the EEG as you are training.
Some useful books for this might be:
-How Nature Works: The Science of Self-organized Criticality: http://www.amazon.co...zed criticality
By the "inventor" of SOC himself . Interesting how a model of sand piles ends up explaining the brain.
-Pocket Guide to Interpersonal Neurobiology: An Integrative Handbook of the Mind: http://www.amazon.co...al neurobiology
It is not directly related to TAG Sync or neurofeedback, but I think this offers the best model I have found so far on the whole brain-mind-relationships interaction. I have found it very useful for understanding neurofeedback and life in general .
It is very well written and easy to read yet extremely informative so I can recommend it. I think the most useful lesson I have gotten out of it is seeing emotions as shifts in integration, using that as a road-map you can move towards increased integration.
-Design in Nature: How the Constructal Law Governs Evolution in Biology, Physics, Technology, and Social Organization: http://www.amazon.co...constructal law
This is also a part of the TAG Sync theory, the constructal law is a proposed new law of physics which explains how flow patterns optimize over time to flow more effectively. You can use this to understand the flow in the brain of energy and information, using neurofeedback you can start engineering more optimized flow patterns.
Anyways I guess that is more than 3-5 .
I am looking forward to reading your report on the sleep trackers, I feel like I really need to start tracking my sleep since it is so important for overall functioning .
I am glad to hear that you got the TLC7ap, I am very curious about the measurable effects of TAG Sync. I think that TAG Sync might increase alpha amplitudes so it would be interesting to see what your observations are on that.
I completed the TLC7ap only after using TAG Sync for 5 months and my alpha amplitudes were extremely high, I think this may be because of the training but I have no way of knowing of course, I could have had high alpha amplitudes before I started using TAG Sync...
