The neural representation of perceived sucrose intensity was contained in the firing rate and spike-timing of a 'small' population of neurons distributed across the Insula and Orbitofrontal taste cortices.
Although sugar-sensing taste neurons typically promote feeding, a taste neuron in the Drosophila pharynx limits feeding via the IR60b receptor; thus, revealing a new element in the circuit logic of feeding control.
The finding that fly maggots, equipped with only 10,000 neurons, process reinforcement not only by value but also by specific quality reveals a basic operating principle of brains and challenges current models of memory organization.
The Sip-Triggered Optogenetic Behavior Enclosure (STROBE) produces robust behaviors via activation of peripheral or central neurons in the fly, and mimics key features of feeding driven by chemical taste ligands.
Open source software enables neuroscientists to integrate single neuron or synaptic-resolution datasets from different imaging modalities to analyse morphology and connectivity at the scale of whole brains and connectomes.
By driving the localized contraction of subcellular muscle regions, a single motor neuron reverses the flow of material in the Caenorhabditis elegans pharynx, a neuromuscular pump, converting feeding into spitting.
A time-course of single nuclei RNA-seq of the mouse placenta identifies trophoblast subtypes and the genes, signaling events, and transcriptional networks important for their differentiation, maintenance, and function.
