A combination of electrochemical neuromodulation of spinal leg circuits and physical training in a robotic rehabilitation system restored volitional locomotion in rodents with severe spinal cord injury.

Advanced recording techniques have enabled the identification of travelling waves of neuronal activity in different areas of the cortex. Sejnowski and colleagues review these findings, consider the mechanisms by which travelling waves are generated and evaluate their possible roles in cortical function.
Surviving threats: neural circuit and computational implications of a new taxonomy of defensive behaviour
Animals exhibit a variety of different responses to threatening stimuli, including both innate and instrumental behaviours. LeDoux and Daw describe a new taxonomy of defensive behaviours and review what we know about the underlying neural circuits and computational processes.
Fibrinogen enters the brain in a wide range of brain diseases that involve blood–brain barrier disruption. In this Review, Petersen et al. discuss recent evidence that fibrinogen causes damage that contributes to the pathology of a range of neurological disorders and discuss therapeutic implications.
The extent and contribution of maternal influence to the developing hypothalamus to later feeding behaviour remain controversial. In this Opinion, Zeltser proposes that crosstalk between developing circuits regulating different modalities of food intake shapes susceptibility to environmental challenges.
