[Fwd: It's gut rhythm and its easy to swallow]

[Thomas Daniel <danielt@u.washington.edu>]

As the stomach churns!


Yes... this talk takes guts!   The stomatogastric ganglion, if you can
stomach it, is an interesting neural net that Kathy Graubard has been
studying for years.  She'll show us its innards in this week's mathbio

We look forward to your undivided attention~!

The stomatogastric nervous system (STNS) is a small neural circuit that
runs the motor programs of chewing, swallowing, and sorting food within
the gut of crabs and lobsters.  The circuit has been intensively studied.
It is small, isolated, easy to record from, and its single complex neural
circuit produces several different motor programs under the control of
neuromodulator inputs.  Many different types of models have been made of
different features of this system and they have been made for varied
purposes.  I will briefly review the basic physiology of the STNS and some
of the different modeling approaches that have been used.  Then I will
discuss in more detail the problem that I am working on (in collaboration
with Dan Hartline), the physiology and simulation methods I use, and our
results so far.
