A narcotic–narcoleptic link

A narcotic–narcoleptic link, Published online: 16 July 2018; doi:10.1038/s41583-018-0043-y

The brains of individuals who have been addicted to opiate drugs show an increase in the number of hypocretin-expressing neurons — the same neurons that are lost in individuals with narcolepsy.

On the nature and use of models in network neuroscience

On the nature and use of models in network neuroscience, Published online: 12 July 2018; doi:10.1038/s41583-018-0038-8

Modern network neuroscience involves the use of various types of models to understand the brain. In this Review, Bassett, Zurn and Gold discuss the aims of this approach before examining how network models may be categorized and validated.

Modelling microglial function with induced pluripotent stem cells: an update

Modelling microglial function with induced pluripotent stem cells: an update, Published online: 05 July 2018; doi:10.1038/s41583-018-0030-3

In recent years, several studies have reported the production of microglia-like cells from induced pluripotent stem cells. Pocock and Piers describe the methods used to produce and analyse these cells and their potential to improve our understanding of microglial function.

The role of engram cells in the systems consolidation of memory

The role of engram cells in the systems consolidation of memory, Published online: 03 July 2018; doi:10.1038/s41583-018-0031-2

Long-term episodic memory storage has been proposed to require a reorganization of neural circuits and networks in a process known as systems consolidation. Tonegawa and colleagues discuss recent advances in our understanding of the contribution of engram cells to this process.

Sleep it off, Published online: 26 June 2018; doi:10.1038/s41583-018-0037-9

A set of 80 (mostly synaptic) proteins show hyperphosphorylation in sleep-deprived mice and genetically ‘sleepy’ mice, suggesting that increased phosphorylation of such proteins may be associated with sleep need.

Neuroscience of apathy and anhedonia: a transdiagnostic approach

Neuroscience of apathy and anhedonia: a transdiagnostic approach, Published online: 26 June 2018; doi:10.1038/s41583-018-0029-9

Anhedonia and apathy are syndromes affecting motivation and have been reported in various neurological and psychiatric disorders. Husain and Roiser examine the neural mechanisms underlying apathy and anhedonia within a transdiagnostic framework of effort-based decision making for reward.

Losing sleep over lipids, Published online: 22 June 2018; doi:10.1038/s41583-018-0033-0

In genetic fly models of Parkinson disease, disrupted lipid trafficking in neuropeptidergic neurons leads to circadian disruption.

Generation of circadian rhythms in the suprachiasmatic nucleus

Generation of circadian rhythms in the suprachiasmatic nucleus

Generation of circadian rhythms in the suprachiasmatic nucleus, Published online: 22 June 2018; doi:10.1038/s41583-018-0026-z

In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus acts as the principal pacemaker for circadian rhythms, which are powerful regulators of physiology and behaviour. In this Review, Hastings, Maywood and Brancaccio examine the molecular, cellular and circuit mechanisms underlying time-keeping in the SCN.

Insights into the molecular and cellular mechanisms by which the APOE4 variant increases risk for Alzheimer disease are gained by comparing transcriptomes of neurons, astrocytes and microglia derived from isogenic APOE3- and APOE4-carrying iPSC cell lines.

Opioid receptors: drivers to addiction?

Opioid receptors: drivers to addiction?, Published online: 22 June 2018; doi:10.1038/s41583-018-0028-x

The opioid system is central to addiction. Darcq and Kieffer review the role of these receptors in the addiction neurocircuitry, ask whether opioid receptors can be targeted to kill pain without addiction and discuss studies that bridge the translational gap in the field.

Specializations for reward-guided decision-making in the primate ventral prefrontal cortex

Specializations for reward-guided decision-making in the primate ventral prefrontal cortex, Published online: 23 May 2018; doi:10.1038/s41583-018-0013-4

Decision-making requires us to correctly evaluate the likely outcomes of our choices. Murray and Rudebeck describe how evidence from lesion and neurophysiology studies in non-human primates has given us insight into the specific contributions of prefrontal cortex subdivisions in this process.
