Article series: Food intake, metabolism and the brain Intermittent metabolic switching, neuroplasticity and brain health Mark P. Mattson et al. p63 | doi:10.1038/nrn.2017.156 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.

Mitochondria at the neuronal presynapse in health and disease Michael J. Devine & Josef T. Kittler p63 | doi:10.1038/nrn.2017.170 Mitochondria may be actively recruited to presynapses to supply energy, buffer calcium and, potentially, fulfil other functions. In this Review, Devine and Kittler examine the importance of this presynaptic population of mitochondria in the maintenance of neuronal homeostasis and how dysfunctional presynaptic mitochondria might contribute to neurodegenerative diseases.

Article series: Food intake, metabolism and the brain Leptin and the maintenance of elevated body weight Warren W. Pan & Martin G. Myers, Jr p95 | doi:10.1038/nrn.2017.168 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.

OPINION Dual function of thalamic low-vigilance state oscillations: rhythm-regulation and plasticity Vincenzo Crunelli et al. p107 | doi:10.1038/nrn.2017.151 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.
