<div dir="ltr"><div><div><div>Thanks John for starting a discussion ... I think we need some. What I liked most about your original post was asking about "What are the underlying principles?" Let's make a list.<br>
</div>Of course, there are so many levels of organizations and mechanisms in the brain, that we might speak about different things; but getting different views would be fun and I think very useful (without the need to offer the only and ultimate).<br>
<br></div>Cheers, Thomas Trappenberg<br><br><br></div>PS: John, I thought you started a good discussion before, but I got discouraged by your polarizing views. I think a lot of us can relate to you, but lhow about letting others come forward now?<br>

While it is true that complete and detailed understanding of neurophysiology and anatomy is at the heart of neuroscience, a lot can be learned about signal propagation in excitable branching structures using statistical physics, and a lot can be learned about information representation and transmission in the brain using mathematical theories about distributed communicating processes. As these modelling approaches have been successfully used in various areas of science, wouldn't you agree that they can also be used to understand at least some of the fundamental properties of brain structures and processes? <br>
