Is Physical Review open access?

On December 7, the Physical Review Journal Club returns with an exclusive conversation with Daniel B. Larremore and Juan G. Restrepo, University of Colorado Boulder on their recently published PRResearch paper: Optimal control of excitable systems near criticality.

To better understand basic aspects of controlling neural activity fluctuations, the researchers numerically and analytically studied a network of binary neurons. Larremore, Restrepo, and colleagues determined how the efficacy of controlling the population firing rate depends on proximity to criticality as well as different structural properties of the network. The team found that control is most effectiveerrors are minimal for the widest range of target firing ratesnear criticality. Optimal control is slightly away from criticality for networks with heterogeneous degree distributions. Thus, while criticality is the noisiest dynamical regime, it is also the regime that is easiest to control, which may offer a way to mitigate the noise.

Larremore and Restrepo will briefly present their results, and then answer any attendee questions during a live question-and-answer session moderated by Raissa DSouza, University of California, Davis, and co-Lead Editor of PRResearch.

Registration is free and a recording of the session will be provided to all registrants.
