Relevance of coherent neural activity for brain functionality
One day workshop to be held on July 28th, 2011
Collective neural oscillations have been observed in many various contexts of brain activity, ranging from ubiquitous gamma-oscillations to theta-rhythm in the hyppocampus, and their role is considered to be crucial for computation and information processing in neural systems. Furthermore, coherent population activities are believed to provide the key mechanism linking sensory stimulation, internal memory, and actual behavior of humans and higher animals. The topic of collective dynamics has been also extensively addressed in mathematical and numerical studies of networks and networks of networks, with a recent emphasis on non-trivial collective dynamics like collective chaos and chimera states. Following the pioneering studies by Abbot and van Vreeswijk on asynchronous states and partial synchronization in neural networks, new non-trivial collective phenomena have been revealed in neural systems with linear and nonlinear synaptic coupling within the last few years.
This workshop aims to provide a forum to discuss state-of-the-art on coherent behaviours in neuronal populations from the point of view of computational neuroscience. The main focus will be to understand the relevance of the observed population dynamics for the brain activity, therefore a frank and open discussion with experimental neuroscientists is planned at the end of the workshop.
The workshop will be organized in 10 presentations of 20 minutes each plus 5 minutes for questions/discussion. A final session of 30 minutes is planned for an ample discussion.
A. Torcini and M. Rosenblum will give a brief introduction and they will chair the final discussion
