    The rapid developmental rise of somatic inhibition disengages hippocampal dynamics from self-motion

    Robin F Dard, Erwan Leprince ... Michel A Picardo
    The first postnatal week ends with the development of perisomatic innervation and with an abrupt switch in the representation of self-motion in the region CA1 of the mouse hippocampus.

    Evaluation of in silico predictors on short nucleotide variants in HBA1, HBA2, and HBB associated with haemoglobinopathies

    Stella Tamana, Maria Xenophontos ... Petros Kountouris
    The calibration of decision thresholds will provide evidence for the optimal use of in silico predictors for the standardised classification of globin gene variants under the American College of Medical Genetics and Genomics/Association for Molecular Pathology framework.

    Experience-dependent shaping of hippocampal CA1 intracellular activity in novel and familiar environments

    Jeremy D Cohen, Mark Bolstad, Albert K Lee
    Comparison of the intracellular activity of hippocampal neurons in novel and familiar environments reveals experience-dependent changes in inputs underlying the formation of stable representations of space.

    Distinct neuronal populations contribute to trace conditioning and extinction learning in the hippocampal CA1

    Rebecca A Mount, Sudiksha Sridhar ... Xue Han
    Large-scale imaging analysis of CA1 reveals that distinct neural networks are involved in trace conditioning versus extinction learning, shedding light on how the hippocampus encodes different types of memory.

    UP-DOWN states and ripples differentially modulate membrane potential dynamics across DG, CA3, and CA1 in awake mice

    Koichiro Kajikawa, Brad K Hulse ... Evgueniy V Lubenov
    The majority of hippocampal neurons in CA3 experience inhibition before and during ripple buildup, while dentate and CA1 cells display depolarizing transients preceding and following ripple onset pointing to a long and orchestrated awake ripple initiation process.

    CA1 pyramidal cell diversity is rooted in the time of neurogenesis

    Davide Cavalieri, Alexandra Angelova ... Rosa Cossart
    Embryonic birthdate is a crucial determinant of heterogeneity among CA1 principal neurons, which include a previously overlooked subpopulation of pioneer neurons.

    Alterations of in vivo CA1 network activity in Dp(16)1Yey Down syndrome model mice

    Matthieu Raveau, Denis Polygalov ... Thomas J McHugh
    CA1 physiology is altered in the hippocampus of Down syndrome mice during both spatial exploration and rest, paralleled by an increase in populations of interneurons responsible for single cell and network synchronization.

    Discovery and characterization of a specific inhibitor of serine-threonine kinase cyclin-dependent kinase-like 5 (CDKL5) demonstrates role in hippocampal CA1 physiology

    Anna Castano, Margaux Silvestre ... Alison D Axtman
    Specific inhibition of cyclin-dependent kinase-like 5 (CDKL5), a kinase linked to a severe neurodevelopmental disorder, demonstrates an important role in the regulation of excitatory hippocampal synapses and synaptic plasticity that was not previously appreciated in rodent knock-out models.

    A native interactor scaffolds and stabilizes toxic ATAXIN-1 oligomers in SCA1

    Cristian A Lasagna-Reeves, Maxime WC Rousseaux ... Huda Y Zoghbi
    Studies in a mouse model of spinocerebellar ataxia type 1 show that a protein called capicua stabilizes toxic ataxin-1 oligomers offering a possible explanation for regional patterns of neurodegeneration.

    Context-dependent requirement of G protein coupling for Latrophilin-2 in target selection of hippocampal axons

    Daniel T Pederick, Nicole A Perry-Hauser ... Liqun Luo
    Latrophilin-2 G protein coupling is required in axons but not target neurons for neural circuit assembly in the mouse hippocampus.
