Development of neuronal networks accounting for cognitive processing

Brain processing during mnemonic and executive tasks relies on interactions within complex neuronal networks. We recently initiated the elucidation of cellular and network mechanisms contributing to the development of functional communication between the prefrontal cortex, hippocampus and subcortical nuclei. The local interactions within prefrontal microcircuits and the long-range coupling during a defined period of development seem to be mandatory for the emergence of cognitive abilities.
