Statistical complexity is maximized close to criticality in cortical dynamics
Nastaran Lotfi, Thaís Feliciano, Leandro A. A. Aguiar +6
Complex systems are typically characterized as an intermediate situation between a complete regular structure and a random system. Brain signals can be studied as a striking exampl…

Signatures of brain criticality unveiled by maximum entropy analysis across cortical states
Nastaran Lotfi, Antonio J. Fontenele, Thaís Feliciano +8
It has recently been reported that statistical signatures of brain criticality, obtained from distributions of neuronal avalanches, can depend on the cortical state. We revisit the…

Global teleconnectivity structures of the El Niño-Southern Oscillation and large volcanic eruptions -- An evolving network perspective
Tim Kittel, Catrin Ciemer, Nastaran Lotfi +4
Recent work has provided ample evidence that global climate dynamics at time-scales between multiple weeks and several years can be severely affected by the episodic occurrence of…
