An array of genetically encoded tools are now available to label and manipulate synapses in different experimental species. Kaang and colleagues provide an overview of these techniques, highlighting their advantages, disadvantages and utility for investigating synaptic function.
During their maturation, mammalian neurons lose the capacity to regrow their axons after an injury. Here, Hilton et al. explore the neuron maturation processes that limit axon regeneration, including changes in gene expression, cytoskeletal dynamics, and intracellular signalling and trafficking.
How the complex functionality of the human brain depends on its underlying white matter architecture is incompletely understood. In this Review, Fotiadis et al. synthesize the heterogeneous macroscale expression of normative structure–function coupling and then discuss how it is affected in neurological and psychiatric conditions.
How the brain routinely processes information from different sensory modalities during everyday tasks is not well understood. In this Perspective, Engel and Senkowski propose how oscillatory neural mechanisms operating at multiple timescales within and across brain networks can mediate such multisensory integration.
Longitudinal precision functional mapping reveals that acute desynchronization of functional connectivity organization induced by the psychedelic psilocybin can persist long-term in the human brain.
Two studies use large-scale genome sequencing data to identify variants in a noncoding gene that cause a neurodevelopmental syndrome in many individuals.
In recent years, genomic studies have identified numerous genetic variants as risk factors for schizophrenia. Sullivan et al. describe our current understanding of the complex genetic architecture of schizophrenia and consider how the genomic findings can be interrogated to boost our understanding of the neurobiology of the disorder.
Acid-sensing ion channel 3 in nociceptors exacerbates inflammation in psoriasis by inducing the release of calcitonin gene-related peptide from these neurons.
A new modelling method developed in male Drosophila melanogaster maps how populations of neurons transform visual stimuli into courtship behaviours without recording neural activity.
The maladaptive reward learning associated with morphine administration is shown here to be mediated by changes in dopamine-release dynamics in reward circuitry resulting from increased myelination specifically in the ventral tegmental area.
Central nervous system (CNS) neurons and glial cells are generated by both direct and indirect neurogenesis. In this Review, Thor outlines the landscape of indirect neurogenesis during CNS development in key species, including humans, and describes the main genetic mechanisms that contribute to its region-specific, neural progenitor cell-specific and temporal control.
There are a number of models that have attempted to explain why people with Parkinson disease move slowly. In this Perspective, Williams identifies the inconsistencies in these models and suggests that these may be addressed by a different model that considers disordered information transmission as fundamental to slow movement development.
The prefrontal cortex is critical for working memory, over a timescale of seconds. In this Review, Miller and Constantinidis examine how the prefrontal cortex facilitates the integration of memory systems across other timescales as well. In this framework of prefrontal learning, short-term memory and long-term memory interact to serve goal-directed behaviour.
