Sleep and memory: Rippling memories
Nature Reviews Neuroscience 17, 739 (2016). doi:10.1038/nrn.2016.154 Author: Sian Lewis Transient, high-frequency hippocampal oscillations called sharp wave–ripples may be involved in the formation of memories that are later consolidated in the neocortex. Oscillations of ripple frequency (∼200 Hz) have been reported in the rodent neocortex during sleep but are not well understood. Here, the authors (Source: Nature Reviews Neuroscience)

Neural development: The river runs through it
Nature Reviews Neuroscience 17, 739 (2016). doi:10.1038/nrn.2016.152 Author: Sian Lewis In humans, some neurons can be detected migrating after birth from the subventricular zone (SVZ) to cortical regions; however, it is not known to what extent these cells mature and become integrated into human forebrain circuits. Here, brain imaging and time-lapse confocal microscopy were used (Source: Nature Reviews Neuroscience)

Nature Reviews Neuroscience 17, 739 (2016). doi:10.1038/nrn.2016.151 Author: Sian Lewis The GGGGCC (G4C2) repeat expansion in the C9orf72 gene is a common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), but the mechanism is unknown. Using quantitative proteomics, the authors found that C9orf72 protein interacts with the actin-binding protein cofilin. Cofilin (Source: Nature Reviews Neuroscience)

The mirror mechanism: a basic principle of brain function
Nature Reviews Neuroscience 17, 757 (2016). doi:10.1038/nrn.2016.135 Authors: Giacomo Rizzolatti & Corrado Sinigaglia The mirror mechanism is a basic brain mechanism that transforms sensory representations of others' behaviour into one's own motor or visceromotor representations concerning that behaviour. According to its location in the brain, it may fulfil a range of cognitive functions, including action and emotion understanding. (Source: Nature Reviews Neuroscience)

Synaptic plasticity: Spinal signals
This study suggests that brain-derived neurotrophic factor (BDNF) is released from dendritic spines in response to activity and acts in an autocrine manner to mediate structural plasticity of the spine from which it was released. (Source: Nature Reviews Neuroscience)

Lasting impact of general anaesthesia on the brain: mechanisms and relevance
Nature Reviews Neuroscience 17, 705 (2016). doi:10.1038/nrn.2016.128 Authors: Laszlo Vutskits & Zhongcong Xie General anaesthesia is usually considered to safely induce a reversible brain state allowing the performance of surgery under optimal conditions. An increasing number of clinical and experimental observations, however, suggest that anaesthetic drugs, especially when they are administered at the extremes of age, can trigger (Source: Nature Reviews Neuroscience)

Circuit modules linking internal states and social behaviour in flies and mice
Nature Reviews Neuroscience 17, 692 (2016). doi:10.1038/nrn.2016.125 Author: David J. Anderson Goal-directed social behaviours such as mating and fighting are associated with scalable and persistent internal states of emotion, motivation, arousal or drive. How those internal states are encoded and coupled to behavioural decision making and action selection is not clear. Recent studies in Drosophila melanogaster (Source: Nature Reviews Neuroscience)

Nature Reviews Neuroscience 17, 671 (2016). doi:10.1038/nrn.2016.147 Author: Sian Lewis Recent evidence suggests that narcolepsy, a disorder that results from the loss of orexinergic neurons of the lateral hypothalamus, has an autoimmune aetiology, but the underlying mechanisms have not been elucidated.
