A mismatch between cell adhesion proteins at the mossy fibre synapse drives female-specific synaptic and cognitive dysfunction in a mouse model of developmental and epileptic encephalopathy 9.
Closure of the critical period of a motor circuit in Drosophila melanogaster larvae is regulated by neuroligin–neurexin signalling between astrocytes and motor neurons.
The impairment of brain fluid homeostasis is a feature of various conditions, highlighting the need to better understand brain water transport for drug development. Here, Nanna MacAulay reviews the molecular mechanisms underlying transmembrane water movement in neurons and glia and across brain barriers, emphasizing the part played by water cotransporters in this process.
Dopamine is often portrayed as a diffuse, slow neuromodulator, yet such signalling cannot explain its broad and sometimes rapid roles. Here, Liu, Goel and Kaeser review recent insights into dopamine release and receptors and present a new framework — the domain-overlap model — for dopamine signalling.
Neuroscience can explain cognition by considering single neurons and their connections (a ‘Sherringtonian’ view) or by considering neural spaces constructed by populations of neurons (a ‘Hopfieldian’ view). In this Perspective, Barack and Krakauer argue that the Hopfieldian view has the conceptual resources to explain cognition more fully the Sherringtonian view.
Evidence suggests that socio-economic status can affect not only the outcome of structural and functional development of the brain but also its rate. Tooley, Bassett and Mackey review this evidence and suggest that the valence and frequency of early experiences interact to influence brain development.
