Connectomic reconstruction of a female Drosophila ventral nerve cord

A Azevedo, E Lesser, JS Phelps, B Mark, L Elabbady… - Nature, 2024 - nature.com
A deep understanding of how the brain controls behaviour requires mapping neural circuits
down to the muscles that they control. Here, we apply automated tools to segment neurons …

Ascending neurons convey behavioral state to integrative sensory and action selection brain regions

CL Chen, F Aymanns, R Minegishi, VDV Matsuda… - Nature …, 2023 - nature.com
Knowing one's own behavioral state has long been theorized as critical for contextualizing
dynamic sensory cues and identifying appropriate future behaviors. Ascending neurons …

Global change in brain state during spontaneous and forced walk in Drosophila is composed of combined activity patterns of different neuron classes

S Aimon, KY Cheng, J Gjorgjieva, ICG Kadow - Elife, 2023 - elifesciences.org
Movement-correlated brain activity has been found across species and brain regions. Here,
we used fast whole brain lightfield imaging in adult Drosophila to investigate the relationship …

Neural circuit mechanisms underlying context-specific halting in Drosophila

N Sapkal, N Mancini, DS Kumar, N Spiller, K Murakami… - Nature, 2024 - nature.com
Walking is a complex motor programme involving coordinated and distributed activity across
the brain and the spinal cord. Halting appropriately at the correct time is a critical component …

Transforming descending input into behavior: The organization of premotor circuits in the Drosophila Male Adult Nerve Cord connectome

HSJ Cheong, K Eichler, T Stürner, SK Asinof… - bioRxiv, 2023 - biorxiv.org
In most animals, a relatively small number of descending neurons (DNs) connect higher
brain centers in the animal's head to circuits and motor neurons (MNs) in the nerve cord of …

[HTML][HTML] Biomechanical origins of proprioceptor feature selectivity and topographic maps in the Drosophila leg

A Mamiya, A Sustar, I Siwanowicz, Y Qi, TC Lu… - Neuron, 2023 - cell.com
Our ability to sense and move our bodies relies on proprioceptors, sensory neurons that
