A new device enables researchers to use and recycle extracellular electrodes (e.g. Neuropixels) for high-yield recordings during freely moving mouse experiments.
Functional imaging and circuit mapping in the Drosophila brain identifies neuropils where sleep-promoting and arousal-promoting neuronal networks converge.
The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
An ancestral apical brain center contributed to the evolution of the insect central complex requiring foxQ2, which is essential for the development of midline structures of the insect brain.
The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.
Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.
Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.
The synaptic connectome of the Drosophila larval visual circuit is the first case of a completely reconstructed visual network in a genetically fully tractable model organism.
Open source software enables neuroscientists to integrate single neuron or synaptic-resolution datasets from different imaging modalities to analyse morphology and connectivity at the scale of whole brains and connectomes.
