GABAergic Inhibition from the Nucleus Tractus Solitarius to Ventrolateral Medulla Phox2b Neurons Modulates Central Respiratory Chemoreflex and Ventilatory Homeostasis - Neuroscience Bulletin Central respiratory chemoreception is a vital homeostatic mechanism maintaining arterial blood gas levels. Central respiratory chemoreceptors in the retrotrapezoid nucleus (RTN) and nucleus tractus so...

Shao et al. demonstrate that activation of #NTS GABAergic neurons suppresses #Phox2b-expressing #RTN neurons, attenuates CO₂-evoked ventilatory responses, and induces hypoventilation. See here: doi.org/10.1007/s122...

Sip smart — science is in your glass.

Chemosensory research from #AChemS members helps explain how our brains interpret complex flavors through taste and smell.

Evolution of taste processing shifts dietary preference - preLights Flies learning to like 'vomit fruit': an example of bitter going from 'yuck' to 'yum.' New research in Drosophila sechellia reveals how taste circuits can evolve to make bitter better. 🍋🪰

A particular species of Drosophila prefers the noni fruit also called “vomit fruit” over more commonly appealing options (bananas, grapes, apples). Why? @tomtom-auer.bsky.social and his colleagues has an answer:

This week @ChabaudChloe is investigating #chemoreception behaviors in the common lizard. This is a first in our lab and will allow to understand how physiology interacts with predator detection.
