The role of neuronal oscillations in computation and communication in multi-scale brain networks

Event Abstract Back to Event The role of neuronal oscillations in computation and communication in multi-scale brain networks Ryan T. Canolty1* 1 University of California at Berkeley, Helen Wills Neuroscience Institute, United States What role do neuronal oscillations play in shaping computation and communication in multi-scale brain networks? Somehow, billions of individual nerve cells coordinate their activity so precisely that it results in a single unified event, such as a toddler taking her first steps, an athlete scoring the perfect goal, or a poet finding just the right word to express the inexpressible. While complex, the neuronal activity required for perception, cognition, and action occurs efficiently and effortlessly. How does this happen? Accumulating evidence suggests that information is dynamically integrated across multiple spatial and temporal scales within the brain, and that a hierarchy of interacting oscillations may help regulate this multi-scale integration. This symposium brings together four researchers who have put these ideas to the test. Peter Lakatos shows that attention-dependent entrainment of oscillatory activity can orchestrate local cortical processing across neuronal ensembles in primary auditory cortex to aid in auditory stream segregation. Laura Lee Colgin demonstrates that gamma rhythms of different frequencies are critical for regulating memory processing in the hippocampus and entorhinal cortex. Andre Bastos presents findings from high density electrocorticography indicating the presence of directed causal interactions between widely-separated brain areas, and shows that these interactions are modulated by attention. Ryan T. Canolty demonstrates that oscillatory phase coupling between multiple cortical regions may coordinate anatomically-dispersed functional cell assemblies. Combined, these talks suggest that neuronal oscillations may play an important causal role in regulating neuronal activity and functional processing within multi-scale brain networks.
