Behavior is a unifying organismal process where genes, neural function, anatomy and
environment converge and interrelate. Here we review the current state and discuss the …

Until the advent of modern neuroscience, free will used to be a theological and a
metaphysical concept, debated with little reference to brain function. Today, with ever …

Scale-free dynamics, with a power spectrum following P∝ f− β, are an intrinsic feature of
many complex processes in nature. In neural systems, scale-free activity is often neglected …

In the absence of salient sensory cues to guide behavior, animals must still execute
sequences of motor actions in order to forage and explore. How such successive motor …

It has been shown recently that a significant portion of brain electrical field potentials
consists of scale-free dynamics. These scale-free brain dynamics contain complex …

It is an open question how animals find food in dynamic natural environments where they
possess little or no knowledge of where resources are located. Foraging theory predicts that …

Animal behaviour is often quantified through subjective, incomplete variables that mask
essential dynamics. Here, we develop a maximally predictive behavioural-state space from …

Chemotaxis is the movement of organisms toward or away from a chemical attractant or
toxin by a biased random walk process. Here we describe the first experimental example of …

Each time a locomoting fly turns, the visual image sweeps over the retina and generates a
motion stimulus. Classic behavioral experiments suggested that flies use active neural …

Interest in L évy walks within the context of movement of organisms has recently soared, with
some now referring to this approach as the L évy walk/flight paradigm. The principal …
