The variation of our motor and cognitive abilities is present at multiple time scales, expanding from periods of tens of milliseconds to hours. The brain-state variability to a large extent is internally coordinated even in the waking brain. This internal coordination is not simply “correlated noise.” Instead, the time-evolving brain states are an important source of mental operations. A brain's current state is, in part, dependent on a prior one. In order to predict the state of a neuronal network, one needs to have access to its recent history. The 1/f brain dynamic is often reflected by a similar 1/f scale freedom of overt behaviors, such as various mental operations and motor outputs. From this perspective, the neuronal “signal” in response to a given environmental perturbation of the brain state is not an initial condition but, rather, a modification of a perpetually evolving network pattern in the brain's landscape.
