I created a new research homepage. Please check it out and give me some feedback.

Thank you Markus Dahlem, the quote by Prof. Cowan made my day. It is wat science is all about. Thanks! Best, Robert

Hi, I am very new to bifurcation analysis. I understand this can be done using XPPaut. But was wondering if this can be done in matlab? have come across matcont - but, again, am a bit sceptical about how 'user friendly' this would be? Any advice would be of much help. thanks.

Greetings to all members of the group.
In my opinion and the opinion of many of my colleagues, namely the dynamic processes determine the cognitive capabilities of neural networks. Therefore, the exchange of information on these topics at the international level, in my opinion is very important.

I like S Coombes 2009-lecture. He showed an elegant presentation of a convolution version in time and space to model waves and an unusual expression for short-range excitation and long-range inhibition...I recommended the lecture too.
It is very good as a qualitative model to understand bump generation and how they propagate and split in space.

Dear all,
Here is one pre_meeting of sfn,"17th Annual Dynamical Neuroscience Satellite Symposium – “Dynamical Disease”
The following is copy-pasted from my email.
Dear Colleague,

As you have attended a recent Dynamical Neuroscience Satellite Symposium, I would like to bring your attention to this year's meeting. Apologies for cross-postings.

Best regards,

Dennis L. Glanzman, Ph.D.

17th Annual Dynamical Neuroscience Satellite Symposium – “Dynamical Disease”

(Preceding the 39th Annual Meeting of the Society for Neuroscience)

Thursday and Friday, October 15-16, 2009

The Buckingham Ballroom of the Allerton Hotel, 701 North Michigan Avenue, Chicago, Illinois

The concept of dynamical diseases has been in existence for over 30 years, with numerous re-views drawing attention to disorders that are characterized by the recurrence of certain symptoms, or exhibit oscillations that appear in the intensity of an ongoing nervous system disease. Neuropsychiatric and neurological diseases exhibiting periodicity or cyclicity include Bipolar Disorder, Schizophrenia, Seasonal Affective Disorder, Klein-Levin Syndrome, Sleep Disorders, Binging, Epilepsy, Multiple Sclerosis, Jet-Lag and Headache. The time course of the disorders can range from seconds and minutes to months and years. This symposium will examine a number of dynamical disorders of the nervous system, with the aim of providing an overarching perspective into potential underlying mechanisms, detection, prevention and treatment strategy.

Confirmed Speakers: Bard Ermentrout, Leon Glass, Isabela Granic, Suzanne Haber, Nancy Kopell, Marc Lewis, Alfred Lewy, Haim Sompolinsky, Peter Tass, Jonathan Victor and Miles Whittington

Keynote Address: Winner of the 2nd Annual Swartz Prize in Computational Neuroscience

Symposium Organizers: Nicholas Schiff, Weill Cornell Medical Center, and Dennis Glanzman, NIMH/NIH

A couple of notes for "CNS vs math modeling" discussion.

CNS is a part of classical math modeling. If you can find analytical solution, you should do this. Otherwise, if your equations are too complex and it is not possible to find analytical solution, you may tray to find solution via numerical methods. Sometimes the latter way is called "simulation". So I would like to stress that the methods are idem in both ways: we describe something in nature by equations and then try to solve it and estimate does our model
represent the modeled object or not. Therefore, in my opinion, a CNS is math modeling for neuroscience and it doesn't matter how you obtain the solution, either analytically or numerically.

I am happy to see new people in this group.

A cordial welcome!

May I suggest that you, at some convenient point, take the time to write what sort of information you expect to read here in the group "nonlinear dynamics"? In particular, issues that might not belong into the broader group "theoretical neuroscience".

I, for example, like to learn about

* upcoming conferences like Dynamics Days, and the earlier the better.

* funding schemes for "nonlinear dynamics"

* planed or recently published books

Hope to hear more ideas, so that this group develops into something useful for us.

I just started to listen to an online talk from Stephen Coombes

Already the way Steve is introduced highlights our discussion.
Also that one of his main research topic is neural fields, a theory invented by Cack Cowan and Hugh Wilson, with whom I started this discussion, is probably not an accident. Mahematical Neuroscience
is very strong in this direction.

And again, that is not to say that CN is in any way less a creative and important approach. Mahematical Neuroscience and CN are even not disjunct but, to my mind, it is also important to be aware of the partly quite different methodologies.
