Title:
Symmetry Breaking and Synchrony
Breaking
 
Abstract: A coupled cell system is a network of interacting
dynamical
systems. Coupled cell models assume that the output from
each cell is important and that signals from two or more
cells can be compared so that patterns of synchrony can
emerge. We ask: Which part of the qualitative dynamics
observed in coupled cells is the product of network
architecture and which part depends on the specific equations?
In our theory, local network symmetries replace symmetry as a way of organizing network dynamics, and synchrony breaking replaces symmetry breaking as a basic way in which transitions to complicated dynamics occur. Background on symmetry breaking and some of the more interesting examples will be presented.

Title: Coupled Systems: Theory &
Examples
 
Abstract: Identically coupled identical systems of
differential equations
lead to a very complex class of (synchronybreaking) bifurcations.
We describe some of the theory and some of the interesting resulting
examples. For example, synchronybreaking Hopf bifurcation in
feedforward chains lead to periodic solutions whose amplitudes
grow much more quickly than the amplitudes in standard Hopf
bifurcation. This observation leads to a tangential discussion of
models of the auditory system.

Title: Geometric Visual
Hallucinations
 
Abstract:
Kluver (circa 1940) proposed that druginduced geometric visual
hallucinations could be divided into four classes or "form constants."
Ermentrout and Cowan (circa 1980) proposed that these form
constants could result from symmetrybreaking pattern formation
on the visual cortex; however only two of the four form constants
were found. Bressloff and Cowan (circa 2000) proposed including
more of the structure of the visual cortex (namely, orientation tuning
and HubelWiesel hypercolumns) in the analysis. This led to the
need for new bifurcation theory results and ultimately to the
four form constants.
