This volume looks at the framework in which different scientific disciplines are integrated into the latest studies in behavioral neurogenetics, and covers new approaches toward understanding the system that controls behavior across the animal kingdom. Chapters in this book cover topics such as mapping brain-wide mesoscale connectome from single animals with BRICseq; gut microbes and Drosophila behavior; bioassaying the function of pheromones in Drosophila melanogaster’s social behavior; automated behavior analysis using a YOLO-based object detection system; and proteomic analysis of C. elegans neurons using TurboID-based proximity labeling. In the Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory.
