Synaptic architecture of leg and wing motor control networks in Drosophila

E Lesser, AW Azevedo, JS Phelps, L Elabbady, A Cook… - bioRxiv, 2023 - biorxiv.org
Animal movement is controlled by motor neurons (MNs), which project out of the central
nervous system to activate muscles. Because individual muscles may be used in many …

Hue selectivity from recurrent circuitry in Drosophila

MP Christenson, A Sanz Diez, SL Heath… - Nature …, 2024 - nature.com
In the perception of color, wavelengths of light reflected off objects are transformed into the
derived quantities of brightness, saturation and hue. Neurons responding selectively to hue …

Mapping model units to visual neurons reveals population code for social behaviour

BR Cowley, AJ Calhoun, N Rangarajan, E Ireland… - Nature, 2024 - nature.com
The rich variety of behaviours observed in animals arises through the interplay between
sensory processing and motor control. To understand these sensorimotor transformations, it …

Spatial patterning controls neuron numbers in the Drosophila visual system

JA Malin, YC Chen, F Simon, E Keefer, C Desplan - Developmental Cell, 2024 - cell.com
Neurons must be made in the correct proportions to communicate with the appropriate
synaptic partners and form functional circuits. In the Drosophila visual system, multiple …

One-to-one mapping between deep network units and real neurons uncovers a visual population code for social behavior

BR Cowley, AJ Calhoun, N Rangarajan, MH Turner… - bioRxiv, 2022 - biorxiv.org

Insights into vision from interpretation of a neuronal wiring diagram

HS Seung - bioRxiv, 2023 - biorxiv.org
What insects can see has been probed by over a century of behavioral experiments. Motion
and color vision have also been studied through neurophysiology in insect brains. Here I …

Two distinct mechanisms of Plexin A function in Drosophila optic lobe lamination and morphogenesis

ME Bustillo, J Douthit, S Astigarraga… - …, 2024 - journals.biologists.com
Visual circuit development is characterized by subdivision of neuropils into layers that house
distinct sets of synaptic connections. We find that, in the Drosophila medulla, this layered …

Divergent neural circuits for proprioceptive and exteroceptive sensing of the Drosophila leg

SYJ Lee, CJ Dallmann, A Cook, JC Tuthill, S Agrawal - bioRxiv, 2024 - biorxiv.org
Somatosensory neurons provide the nervous system with information about mechanical
forces originating inside and outside the body. Here, we use connectomics to reconstruct …

Interneuron diversity and normalization specificity in a visual system

HS Seung - bioRxiv, 2024 - biorxiv.org
Normalization is a fundamental operation in image processing. Convolutional nets have
evolved over the past decade to include a large number of normalizations, and this …

Super Bowl, an open platform for visual stimulation of insects

S Prech, LN Groschner, A Borst - bioRxiv, 2023 - biorxiv.org
To study how the nervous system processes visual information, experimenters must record
neural activity while delivering visual stimuli in a controlled fashion. In animals with a nearly …
