2. Key Issue
Given a large-scale distributed anatomical architecture composed of functionally differentiated areas, how can a spatiotemporal network dynamics arise that is capable of capturing detailed cognitive architectures and dynamics?
Foci of this session
Neuronal population dynamics (local)
Functionally relevant large-scale network dynamics (global)

3. Low-dimensional description of population dynamics
Anatomical and functional architectures
based on a distributed population variable (x,t)
Local architectures:
Can we substitute the detailed neuronal dynamics Q(t)
by a lower-dimensional population variable such as a field (x,t) ?
