    Although leptin administration decreases food intake and body weight in lean mice, it has no effect in obese mice. In this Review, Pan and Myers discuss how leptin action becomes dysfunctional in obesity and suggest that elevated leptin levels promote processes that limit leptin action.

    During low-vigilance states, thalamic neurons exhibit diverse rhythmic activities that contribute to specific parts of the electroencephalogram rhythm. In this perspective, Crunelli and colleagues propose that thalamic oscillations of these low-vigilance states also have a plasticity function that modifies the strength of excitatory and inhibitory synapses in local neuronal assemblies.

    Eating patterns in modern societies often preclude the metabolic switch from utilization of glucose to ketones as a cellular energy source. In this Review, Mattson and colleagues discuss how intermittent metabolic switching impacts brain function and vulnerability to injury and disease.

    The brain comprises complex structural and functional networks, but much remains to be determined regarding how these networks support the communication processes that underlie neuronal computation. In this Review, Avena-Koenigsberger, Misic and Sporns discuss the network basis of communication dynamics in the brain.

    The brain uses predictable temporal structure to anticipate and select relevant events in time. Nobre and van Ede introduce different types of this 'temporal expectation' and its neural underpinnings, and describe how temporal expectation interacts with other forms of expectation in guiding adaptive behaviour.

    Activity-driven changes in gene transcription regulate synaptic development and function. Bading and colleagues describe recent evidence of lineage-specific changes in the gene regulatory regions that govern excitation–transcription coupling and consider how such changes may have contributed to the evolution of human cognitive abilities.
