Abstract

To track and characterize the temporal dynamics of functional interdependence among cortical areas, we developed an adaptive multivariate autoregressive (AMVAR) modeling approach to the analysis of multichannel event-related local field potentials (LFPs) in macaque monkeys. We demonstrate the effectiveness of the approach by showing event-related dynamic change of power, coherence and directed transfer functions derived from the AMVAR models during a cognitive task.
