Driver lines for studying associative learning in .

The mushroom body (MB) is the center for associative learning in insects. In , intersectional split-GAL4 drivers and electron microscopy (EM) connectomes have laid the foundation for precise interrogation of the MB neural circuits. However, investigation of many cell types upstream and downstream of the MB has been hindered due to lack of specific driver lines.

A split-GAL4 driver line resource for neuron types.

Techniques that enable precise manipulations of subsets of neurons in the fly central nervous system (CNS) have greatly facilitated our understanding of the neural basis of behavior. Split-GAL4 driver lines allow specific targeting of cell types in and other species. We describe here a collection of 3060 lines targeting a range of cell types in the adult CNS and 1373 lines characterized in third-instar larvae.

STEERING FROM THE REAR: COORDINATION OF CENTRAL PATTERN GENERATORS UNDERLYING NAVIGATION BY ASCENDING INTERNEURONS.

Understanding how animals coordinate movements to achieve goals is a fundamental pursuit in neuroscience. Here we explore how neurons that reside in posterior lower-order regions of a locomotor system project to anterior higher-order regions to influence steering and navigation. We characterized the anatomy and functional role of a population of ascending interneurons in the ventral nerve cord of larvae.

Motor neurons generate pose-targeted movements via proprioceptive sculpting.

Motor neurons are the final common pathway through which the brain controls movement of the body, forming the basic elements from which all movement is composed. Yet how a single motor neuron contributes to control during natural movement remains unclear. Here we anatomically and functionally characterize the individual roles of the motor neurons that control head movement in the fly, Drosophila melanogaster.

The landscape of non-psychotic psychiatric illness in rural Canada: a narrative review.

Introduction: Canada's rural population has diverse demographic features and accounts for 18.9% of Canada's population. Indigenous Peoples (First Nations, Inuit, and Métis), who are highly represented in rural communities, have additional risk factors related to colonialism, and historical and ongoing trauma.
