Mathematicians and physicists have recently devoted a great deal of
effort towards the understanding of synchronization and emerging
collective phenomena in complex networks of many interacting
elements. Neuronal networks of the central nervous system are
prototypical examples of this class of systems. Collective phenomena
that emerge in such networks are currently investigated by both
experimental and theoretical neuroscientists. Synchronization
phenomena are a prominent example of collective phenomena that have
been observed in many different brain structures and behavioral
contexts, under both physiological and pathological
conditions. Synchronized oscillations have received particular
attention because they are prominent in the cortex of the awake brain
during attention, and have been implicated in higher level processes,
such as sensory binding, awareness, storage of memories, and even
consciousness. From the clinical point of view, abnormal
synchronization seems to play a crucial role in important neural
disorders such as Parkinson, epilepsy and essential tremor. However,
fundamental questions about such synchronized phenomena still need to
be answered: What are the mechanisms leading to synchrony in neuronal
systems? What are the functional roles, if any, of synchronization
phenomena?  How can abnormal synchronization be avoided or controlled?
 
An active collaboration among researchers working in dynamical systems
and complexity theory with neuroscientists is essential to make
substantial progress in the understanding of such mechanisms.  Such
dialogue is all the more needed given recent progresses in
experimental techniques, which now provide an unprecedented view of
the dynamics of brain networks. For example, it is now possible to
collect data about the activity of large ensembles of cells, to
understand the interrelationships between activity in different brain
structures, with a detailed mapping of the connections between those
areas, and to probe the effect of particular genes and molecules on
the dynamical behavior of biological neural networks.  Experiments in
cognitive neuroscience have demonstrated how dynamical phenomena, such
as information carrying modulations of neural coherence, phase coding,
etc. play a decisive role in the encoding and processing of
information.  These experimental data represent at the same time the
motivation and the validating benchmark for quantitative models of
brain functioning that use concepts and tools from dynamical
systems. Moreover, nonlinear time-series techniques are needed to
extract meaningful information from experimental data, e.g.:
multivariate measures are essential to study the relationships between
simultaneously recorded signals.
 
The main topics addressed by the workshop include:
 * Synchronization in low and high dimensional systems; 
 * Emergence of collective dynamics in networks; 
 * Nonlinear data analysis: univariate, bivariate and multivariate measures; 
 * Modeling of neuronal networks: dynamical and topological aspects; 
 * Study of the dynamics of neural circuits, in vitro and in vivo approaches; 
 * Control and modelling of brain oscillations and rhythms;
 * Large scale, inter-structure coherence and synchronization: 
   evidence from human MEG and EEG data
 
 
Aims of the workshop
The aim of the workshop is to strenghten the communication
channels between the (overlapping) communities of dynamical systems
theorists, computational and experimental neuroscientists, in order to
stimulate fruitful interactions and exchanges of ideas.  In particular, 
it aims to put into contact researchers working in nonlinear dynamics and
time series and pattern analysis, together with computational
neuroscientists involved in the study of realistic neuronal circuits,
together with experimentalists that are characterizing, with the help
of modern technologies, the nature of interactions in neural networks,
and the cellular and molecular basis of synchronization in such
networks.
 
 
APPLICATIONS
The participation to the workshop is open to everybody who is just
interested in following the lectures and talks, in this case no
application is needed.
 
However, those who want to be actively involved in the workshop with
presentations, discussions etc. should apply by filling the form
"Interest in Participation" before  March 1st, 2008. A selection will be
performed by the organizers and the notification of the final decision
will be sent to the applicants by March 15, 2008. Only at this date it
will be possible to decide the kind of presentation (oral or poster)
for the selected candidates.  Please notice that, in order to preserve
much free time for informal discussions and joint research work, only
few oral presentations will be scheduled.
 
No fee is required, but no financial support can be given to applicants due to budgetary restraints.
