Scope of the workshop
Is the traditional view on brain activity dynamics, in which the cognitive
flow of information wanders through multiple stable states driven by task–
dependent inputs, still a robust model? This picture has been recently
challenged both empirically and from the modelling perspective. In this
workshop we will address a range of recent complementary views of
cortical activity dynamics.
In several contemporary models, intrinsic activity fluctuations drive default
transitions between metastable states shaped by anatomical connectivity,
even in the absence of external stimuli. Noise enriches the dynamical
repertoire of deterministic states; creating flexible "ghost" attractors which
permit the effective processing of task–related cognitive entities. Another
proposed metaphor of transient brain dynamics consisted of successions
of metastable saddle states; dynamical objects which are particularly
reliable but form which neural activity eventually switches among them,
even without the intervention of noise.
In this workshop we will have modelling and data analysis contributions
which focus on metastable activity dynamics, analyses of non–stationary
neural recordings and transient dynamics during cognitive processing. The
next topics will be discussed:

Attracting and transient dynamics of neural ensembles

Non–stationary neural recordings and data analyses

Cortical activity dynamics at resting state

Transient dynamics during perception

Travelling waves in cortex

Cognitive processing dynamics.

This event will take place on the July 17 2013.
