Oh #Drosophila , never change.
The gene "degrees of kevin bacon (dokb)" has polymorphisms present that regulate social network behaviour.
"We named this gene degrees of kevin bacon (dokb) after the parlor game “Six Degrees of Kevin Bacon” where participants choose an arbitrary Hollywood actor and determine the shortest path that connects that individual to Kevin Bacon via film roles."

The gene “degrees of kevin bacon” (dokb) regulates a social network behaviour in Drosophila melanogaster - Nature Communications
The structure of a social network is thought to be heritable in many animals, including humans. Here, Rooke and colleagues identify a gene, which they name “degrees of kevin bacon (dokb)”, that is expressed in the central nervous system of Drosophila…Nature
I'm happy to present the last paper from my thesis!
Lisa Li and I set out to build a model of fly walking which is based on 3D kinematics data, handles perturbations, and includes sensorimotor delays. (This was supervised by Bing Brunton and @tuthill )
We set up a new modeling framework, generated fly walking with kinematics matched to real data, a simple metric for quantifying similarity of trajectories, and found constraints on delays for robust walking!

Sensorimotor delays constrain robust locomotion in a 3D kinematic model of fly walking
Walking animals must maintain stability in the presence of external perturbations, despite significant temporal delays in neural signaling and muscle actuation.bioRxiv
An open platform for visual stimulation of insects
To study how the nervous system processes visual information, experimenters must record neural activity while delivering visual stimuli in a controlled fashion.doi.org
Nice to see this fantastic follow up from Stephane @dissel_lab1 clarifying the role of dFB in #Drosophila #sleep,

The dorsal fan-shaped body is a neurochemically heterogeneous sleep-regulating center in Drosophila
Sleep is a behavior that is conserved throughout the animal kingdom. Yet, despite extensive studies in humans and animal models, the exact function or functions of sleep remain(s) unknown.bioRxiv
