We explore synchronization in networks of coupled nonlinear oscillators in our laboratory. Numerical models are developed and simulations are compared with experimental observations to understand how real networks synchronize and desynchronize as coupling coefficients are varied. Convergence to synchrony is found to depend on the network topology. Next, we report results of experiments on coupled map lattices with liquid crystal spatial light modulators and the observation of chimera-like states when nonlocal coupling is realized. The relevance of such states to neuronal networks will be discussed.
