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.

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.

A study finds that microglia depletion has no effect on experience-dependent maturation of visual cortex circuitry in mice.

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.
