A computational model for the control of chemotaxis in the Drosophila larva clarifies the link between the peripheral encoding of naturalistic olfactory stimuli and action selection.

A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.

Selection for undifferentiated multicellularity emerges in an evolutionary cell-based model because a collective of cells performs chemotaxis better than single cells in a noisy environment.

Task controllability manipulations reveal that information seeking is associated with reduced confidence and active hypothesis testing, as well as stronger neurophysiological correlates of attention and arousal.

An experimentally supported model of grid cells naturally enables them to participate in firing sequences that encode rapid trajectories in space.

Neurons in prefrontal cortex track the variance of experienced rewards to guide economic decisions.

Humans supplement complex, resource-demanding strategies with simple heuristics for solving the exploration-exploitation dilemma, and noradrenaline functioning controls their utilisation.

Simple mathematical reasoning shows that the large amount of synaptic turnover seen in many parts of the brain is in fact optimal for memory retention.
