DOI: 10.1002/cne.25152
Abstract: In one species of shore crab (Brachyura, Varunidae), a center that supports long‐term visual habituation and that matches the reniform body's morphology has been claimed as a homolog of the insect mushroom body despite lacking… read more here.

DOI: 10.1016/j.bbrc.2017.04.150
Abstract: Axonal branching is a fundamental requirement for sending electrical signals to multiple targets. However, despite the importance of axonal branching in neural development and function, the molecular mechanisms that control branch formation are poorly understood.… read more here.

DOI: 10.1016/j.cell.2017.04.028
Abstract: Animals exhibit a behavioral response to novel sensory stimuli about which they have no prior knowledge. We have examined the neural and behavioral correlates of novelty and familiarity in the olfactory system of Drosophila. Novel… read more here.

DOI: 10.1038/s41467-019-09262-2
Abstract: Macroautophagy is an evolutionarily conserved cellular maintenance program, meant to protect the brain from premature aging and neurodegeneration. How neuronal autophagy, usually loosing efficacy with age, intersects with neuronal processes mediating brain maintenance remains to… read more here.

DOI: 10.1038/s41586-020-2997-y
Abstract: Sleep remains a major mystery of biology, with little understood about its basic function. One of the most commonly proposed functions of sleep is the consolidation of memory 1 – 3 . However, as conditions… read more here.

DOI: 10.1038/s41598-021-99531-2
Abstract: Sleep is a fundamental behavioral state important for survival and is universal in animals with sufficiently complex nervous systems. As a highly conserved neurobehavioral state, sleep has been described in species ranging from jellyfish to… read more here.

DOI: 10.1073/pnas.2111283119
Abstract: Significance The adult Drosophila mushroom body (MB) is one of the most extensively studied neural circuits. However, how its circuit organization is established during development is unclear. In this study, we provide an initial characterization… read more here.

DOI: 10.1098/rsbl.2019.0084
Abstract: In insects, odours are coded by the combinatorial activation of ascending pathways, including their third-order representation in mushroom body Kenyon cells. Kenyon cells also receive intersecting input from ascending and mostly dopaminergic reinforcement pathways. Indeed,… read more here.

DOI: 10.1098/rsob.220096
Abstract: The principles of how brain circuits establish themselves during development are largely conserved across animal species. Connections made during embryonic development that are appropriate for an early life stage are frequently remodelled later in ontogeny… read more here.

DOI: 10.1101/2022.06.09.495452
Abstract: Insects like Drosophila produce a second brain adapted to the form and behavior of a larva. Neurons for both larval and adult brains are produced by the same stem cells (neuroblasts) but the larva possesses… read more here.
