the exact contribution of the thalamus to these interactions remains unclear. Recent studies …

Chimera states: coexistence of coherence and incoherence in networks of coupled oscillators

MJ Panaggio, DM Abrams - Nonlinearity, 2015 - iopscience.iop.org
A chimera state is a spatio-temporal pattern in a network of identical coupled oscillators in
which synchronous and asynchronous oscillation coexist. This state of broken symmetry …
