    Two conserved vocal central pattern generators broadly tuned for fast and slow rates generate species-specific vocalizations in Xenopus clawed frogs

    Ayako Yamaguchi, Manon Peltier
    Although courtship vocalizations are unique to each species, the basic architecture of the neural circuitries underlying this behavior is conserved among closely related species of frogs, suggesting behavior can diverge while utilizing the homologous neural network inherited through evolutionary lineage.

    Development of frequency tuning shaped by spatial cue reliability in the barn owl’s auditory midbrain

    Keanu Shadron, José Luis Peña
    The juvenile barn owl displays wide heterogeneity in tuning properties in the auditory midbrain, which is shaped during development to match the pattern of sensory statistics experienced in early life and maintained into adulthood.

    Early-life experience reorganizes neuromodulatory regulation of stage-specific behavioral responses and individuality dimensions during development

    Reemy Ali Nasser, Yuval Harel, Shay Stern
    Early-life experiences and neuromodulatory mechanisms shape discontinuous behavioral plasticity across developmental stages and modify the spectrum of long-term individuality patterns within isogenic populations.

    Instantaneous antidepressant effect of lateral habenula deep brain stimulation in rats studied with functional MRI

    Gen Li, Binshi Bo ... Xiaojie Duan
    Electrical stimulation at the lateral habenula causes an instantaneous remission of depressive symptoms in two rat models, with more medial stimulation sites exhibiting greater antidepressant effects than more lateral stimulation sites, as revealed by functional MRI studies.

    APOE expression and secretion are modulated by mitochondrial dysfunction

    Meghan E Wynne, Oluwaseun Ogunbona ... Victor Faundez
    Current models of Alzheimer's disease that put mitochondria as an endpoint of disease should be reconsidered because genetic defects affecting mitochondria by themselves can also regulate Alzheimer’s disease risk factor apolipoprotein E (APOE) expression and secretion.

    The nematode worm C. elegans chooses between bacterial foods as if maximizing economic utility

    Abraham Katzen, Hui-Kuan Chung ... Shawn R Lockery
    A worm with a nervous system of only 302 neurons satisfies the necessary and sufficient conditions for value-based decision making.

    Spatiotemporal neural dynamics of object recognition under uncertainty in humans

    Yuan-hao Wu, Ella Podvalny, Biyu J He
    Combining 7 Tesla fMRI and MEG data collected during a challenging visual recognition task revealed distinct neural representational formats in ventral visual and frontoparietal regions, and the emergence of recognition-related signals prior to category-related information.

    Mating activates neuroendocrine pathways signaling hunger in Drosophila females

    Meghan Laturney, Gabriella R Sterne, Kristin Scott
    Postmated increases in sucrose consumption in Drosophila melanogaster females is executed by a female specific circuit that alters neuroendocrine centers to promote hunger.

    The normalization model predicts responses in the human visual cortex during object-based attention

    Narges Doostani, Gholam-Ali Hossein-Zadeh, Maryam Vaziri-Pashkam
    A normalization model is shown to predict responses to multiple objects across changes in the attentional state in the visual cortex, providing evidence for the role of normalization as a fundamental operation in the human brain.

    Task-evoked metabolic demands of the posteromedial default mode network are shaped by dorsal attention and frontoparietal control networks

    Godber M Godbersen, Sebastian Klug ... Andreas Hahn
    In the human brain, default mode network BOLD deactivations can be accompanied by both increases and decreases in glucose metabolism, depending on the respective metabolic demands of task-positive cognitive control and attention networks.
