A new study describes opposing cell-specific RhoA-dependent mechanisms linking the intrinsic regulation of neuronal microtubule dynamics and the extrinsic regulation of reactive astrocyte signalling that restrain axon regeneration.
Cortical–subcortical fusion organoids replicate complex features of human brain activity and are used to explore altered network function in Rett syndrome.
The raphe nucleus contains specific populations of serotonergic neurons that express either orexin type 1 or type 2 receptors that directionally regulate plasma glucose and peripheral energy metabolism.
Neural circuits in the mammalian central nervous system are modified in response to neural activity during development. In this Review, Faust and colleagues provide an overview of the mechanisms underlying developmental synaptic pruning and how alterations in this process can occur in neurodevelopmental disorders such as autism spectrum disorder and schizophrenia.
Male-only studies predominate preclinical research on anxiety and depression. In this Review, Bangasser and Cuarenta discuss how, since the inclusion of female subjects, new mechanisms have been identified that underlie vulnerability to these disorders, and that reveal novel targets for treatments.
The sympathetic regulation of bodily functions relies on precise connections between sympathetic neurons and peripheral organs. In this Review, Scott-Solomon and colleagues discuss the mechanisms underlying the development of the sympathetic nervous system and provide insight into disorders regulated by this branch of the nervous system.
Developing a better understanding of neural codes should enable the links between stimuli, brain activity and behaviour to become clearer. In this Perspective, Kriegeskorte and Wei examine neural tuning and representational geometry — complementary approaches used to understand neural codes — and the relationship between them.
