    "abstract": "Many complex systems display self-organized critical states characterized by\n1/f frequency scaling of power spectra. Global variables such as the\nelectroencephalogram, scale as 1/f, which could be the sign of self-organized\ncritical states in neuronal activity. By analyzing simultaneous recordings of\nglobal and neuronal activities, we confirm the 1/f scaling of global variables\nfor selected frequency bands, but show that neuronal activity is not consistent\nwith critical states. We propose a model of 1/f scaling which does not rely on\ncritical states, and which is testable experimentally.",
