A diverse group of scientists interest in topics ranging from interoception to sensory driven navigation, long time scales shaping motor and mental states & with a strong bias for aquatic life at day and night.
Downstream @etlunsford.bsky.social mapped how the corresponding interneurons in the brainstem project onto reticulospinal neurons to select the steering command eliciting either forward or turns ... recalling the pioneering work of @daniobrain.bsky.social on optical motor response to flow! (5)

By combining controlled mechanical stimulation & whole brain #imaging, @etlunsford.bsky.social revealed an essential principle 💡... Mechanosensory inputs from any directions along the body are encoded relative to the center of mass (COM)! Recalling #olfaction with odors encoded by pleasantness (4)

The tackle this question, @etlunsford.bsky.social 🌬️ stimulated each & all neuromasts along the body & discovered a simple principle within the brainstem !! Namely, information on location & direction is encoded in an egocentric referential around the center of mass! www.biorxiv.org/content/10.1...

Fish display mechanosensors called neuromasts covering their body from head to tail. In each neuromast, hair cells can sense changes in water flow along different directions in the anteroposterior axis, either tailward or headward. How does the brain compute the flow information across the body? (2)

Let's share @etlunsford.bsky.social's work : to survive, animals avoid drifting involuntarily in their environment. While humans rely on visual & vestibular cues, birds & fish need to sense complex flow changes of the external fluid (air/water) around them to select motor actions. How do they do?(1)

Hola, Hello, Bonjour, Bonjourno, Guten tag BlueSky oasis! Loving art, music, cinema, we are a group of scientists found of animal behavior & physiology, using optical tricks in transparent fish to decipher dynamic neuronal codes underlying sensorimotor integration during navigation & morphogenesis!
