TTool: A Supervised Artificial Intelligence-Assisted Visual Pose Detector for Tool Heads in Augmented Reality Woodworking

Yves Weinand, Andrea Settimi, Julien Gamerro, Florian Aymanns, Naravich Chutisilp

We present TimberTool (TTool v2.1.1), a software designed for woodworking tasks assisted by augmented reality (AR), emphasizing its essential function of the real-time localization of a tool head’s poses within camera frames. The localization process, a fu ...

Harmonizing sound and light: X-ray imaging unveils acoustic signatures of stochastic inter-regime instabilities during laser melting

Roland Logé, Florian Aymanns, Milad Hamidi Nasab

Laser powder bed fusion (LPBF) is a metal additive manufacturing technique involving complex interplays between vapor, liquid, and solid phases. Despite LPBF's advantageous capabilities compared to conventional manufacturing methods, the underlying physica ...

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

Pavan P Ramdya, Florian Aymanns, Nicolas Talabot, Chin-Lin Chen

Knowing one's own behavioral state has long been theorized as critical for contextualizing dynamic sensory cues and identifying appropriate future behaviors. Ascending neurons (ANs) in the motor system that project to the brain are well positioned to provi ...

Microengineered devices enable long-term imaging of the ventral nerve cord in behaving adult Drosophila

Mahmut Selman Sakar, Pavan P Ramdya, Florian Aymanns, Victor Lobato Rios, Murat Kaynak, Semih Günel, Chin-Lin Chen, Laura Joan Hermans, Jonas Friedrich Braun

The dynamics and connectivity of neural circuits continuously change on timescales ranging from milliseconds to an animal's lifetime. Therefore, to understand biological networks, minimally invasive methods are required to repeatedly record them in behavin ...

Descending neuron population dynamics during odor-evoked and spontaneous limb-dependent behaviors

Pavan P Ramdya, Florian Aymanns, Chin-Lin Chen

Deciphering how the brain regulates motor circuits to control complex behaviors is an important, long-standing challenge in neuroscience. In the fly, Drosophila melanogaster, this is coordinated by a population of similar to 1100 descending neurons (DNs). ...

Overcoming the Domain Gap in Neural Action Representations

Pascal Fua, Pavan P Ramdya, Florian Aymanns, Semih Günel, Sina Honari

Relating behavior to brain activity in animals is a fundamental goal in neuroscience, with practical applications in building robust brain-machine interfaces. However, the domain gap between individuals is a major issue that prevents the training of genera ...

Uncovering the neural substrates of communication between the brain and ventral nerve cord in Drosophila melanogaster (italic)

Florian Aymanns

Despite a long history of research in motor control, the exact mechanism of how the brain communicates with the the invertebrate ventral nerve cord (VNC) and the vertebrate spinal cord on a single neuron basis remains largely elusive. Drosophila melanogast ...

EPFL2022

Imaging neural activity in the ventral nerve cord of behaving adult Drosophila

Michaël Unser, Pavan P Ramdya, Chin-Lin Chen, Florian Aymanns, Denis Fortun, Laura Joan Hermans

To understand neural circuits that control limbs, one must measure their activity during behavior. Until now this goal has been challenging, because limb premotor and motor circuits have been largely inaccessible for large-scale recordings in intact, movin ...
