An integrated anatomical, functional and evolutionary view of the Drosophila olfactory system.
The Drosophila melanogaster olfactory system is one of the most intensively studied parts of the nervous system in any animal. Composed of ~50 independent olfactory neuron classes, with several associated hygrosensory and thermosensory pathways, it has been subject to diverse types of experimental analyses. However, synthesizing the available information is limited by the incomplete data and inconsistent nomenclature found in the literature. In this work, we first "complete" the peripheral sensory map through the identification of a previously uncharacterized antennal sensory neuron population expressing Or46aB, and the definition of an exceptional "hybrid" olfactory neuron class comprising functional Or and Ir receptors. Second, we survey developmental, anatomical, connectomic, functional, and evolutionary studies to generate an integrated dataset and associated visualizations of these sensory neuron pathways, creating an unprecedented resource. Third, we illustrate the utility of the dataset to reveal relationships between different organizational properties of this sensory system, and the new questions these stimulate. Such examples emphasize the power of this resource to promote further understanding of the construction, function, and evolution of these neural circuits.
期刊介绍:
EMBO Reports is a scientific journal that specializes in publishing research articles in the fields of molecular biology, cell biology, and developmental biology. The journal is known for its commitment to publishing high-quality, impactful research that provides novel physiological and functional insights. These insights are expected to be supported by robust evidence, with independent lines of inquiry validating the findings.
The journal's scope includes both long and short-format papers, catering to different types of research contributions. It values studies that:
Communicate major findings: Articles that report significant discoveries or advancements in the understanding of biological processes at the molecular, cellular, and developmental levels.
Confirm important findings: Research that validates or supports existing knowledge in the field, reinforcing the reliability of previous studies.
Refute prominent claims: Studies that challenge or disprove widely accepted ideas or hypotheses in the biosciences, contributing to the correction and evolution of scientific understanding.
Present null data: Papers that report negative results or findings that do not support a particular hypothesis, which are crucial for the scientific process as they help to refine or redirect research efforts.
EMBO Reports is dedicated to maintaining high standards of scientific rigor and integrity, ensuring that the research it publishes contributes meaningfully to the advancement of knowledge in the life sciences. By covering a broad spectrum of topics and encouraging the publication of both positive and negative results, the journal plays a vital role in promoting a comprehensive and balanced view of scientific inquiry.
