How do billions of neurons cooperate to process information and mediate cognitive function such as learning, planning or memory? An influential hypothesis is that groups of neurons can synchronize within brief time windows to represent a cognitive entity or a concept (e.g. an apple, a sonata, the thought of my grand-mother; Hebb 1949). These groups, called `cell assemblies’ are thought to be the functional units of the brain. Recent advances in large-scale neuronal recordings enabled to investigate such synchronous activity within single areas of the brain. Yet, the functional relevance of these ensembles remains largely unexplored, especially in higher order brain areas. To address this question, we designed two research projects based on ...
