    Hippocampal replay of experience at real-world speeds

    Eric L Denovellis, Anna K Gillespie ... Loren M Frank
    A new state space decoder revealed that most hippocampal sharp-wave ripples contain coherent spatial content, and that this 'replay' typically progresses at speeds similar to those seen during actual experiences.

    Decoding the brain state-dependent relationship between pupil dynamics and resting state fMRI signal fluctuation

    Filip Sobczak, Patricia Pais-Roldán ... Xin Yu
    The variability of the pupil–fMRI relationship was characterized through a combination of clustering and prediction methods, which revealed brain state-specific subcortical and neuromodulatory activation patterns reflected in pupil dynamics.

    Task-specific roles of local interneurons for inter- and intraglomerular signaling in the insect antennal lobe

    Debora Fusca, Peter Kloppenburg
    In the antennal lobe of insects, nonspiking local interneurons play a crucial role in intraglomerular signaling.

    Dendritic osmosensors modulate activity-induced calcium influx in oxytocinergic magnocellular neurons of the mouse PVN

    Wanhui Sheng, Scott W Harden ... Charles J Frazier
    Activity-induced dendritic calcium influx in oxytocinergic magnocellular neurons can be robustly modulated by a highly diverse set of stimuli acting on distinct types of ion channels expressed along the dendritic membrane.

    Dorsal premammillary projection to periaqueductal gray controls escape vigor from innate and conditioned threats

    Weisheng Wang, Peter J Schuette ... Avishek Adhikari
    Activity in the hypothalamic dorsal premammillary nucleus predicts future escape from threat, represents escape velocity, and controls escape velocity via a projection to the brainstem.

    A unified platform to manage, share, and archive morphological and functional data in insect neuroscience

    Stanley Heinze, Basil el Jundi ... Kevin Tedore
    The InsectBrain Database is a novel, freely available software tool designed to accelerate research in the field of insect neuroscience and to improve implementation of open data concepts.

    Heterogeneous side effects of cortical inactivation in behaving animals

    Ariana R Andrei, Samantha Debes ... Valentin Dragoi
    Focal optogenetic inactivation of cortex induces complex changes in neural responses outside the targeted area that can influence behavioral performance.

    Coherent theta activity in the medial and orbital frontal cortices encodes reward value

    Linda M Amarante, Mark Laubach
    The more you want it or the better it is, the stronger is medial frontal theta (paraphrased from a retweet of the preprint by Dr James Hyman).

    A zebrafish screen reveals Renin-angiotensin system inhibitors as neuroprotective via mitochondrial restoration in dopamine neurons

    Gha-Hyun J Kim, Han Mo ... Su Guo
    In vivo dopamine neuron imaging-based neuroprotective small molecule screen in larval zebrafish and mechanistic investigation using conditional CRISPR knockout and cell-type-specific RNA-seq analysis, coupled with cross-species analyses including human clinical data interrogation, uncover potential disease-modifying therapeutics for Parkinson's disease (PD).

    DeepEthogram, a machine learning pipeline for supervised behavior classification from raw pixels

    James P Bohnslav, Nivanthika K Wimalasena ... Christopher D Harvey
    DeepEthogram automatically classifies animal behavior videos into researcher-defined behaviors of interest, saving researcher time and enabling more detailed downstream analysis of behavior.
