    Distinct representation of cue-outcome association by D1 and D2 neurons in the ventral striatum’s olfactory tubercle

    Nuné Martiros, Vikrant Kapoor ... Venkatesh N Murthy
    Real-time imaging of neural activity in behaving mice reveals that the two canonical types of neurons in the olfactory tubercle carry distinct information about learned odor cues, with D1 neurons representing stimulus valence and D2 neurons mainly representing stimulus identity.

    Developmental emergence of two-stage nonlinear synaptic integration in cerebellar interneurons

    Celia Biane, Florian Rückerl ... Laurence Cathala
    Patch-clamp electrophysiology, fluorescence imaging, and computational modeling were used to identify cellular mechanisms underlying maturation of dendritic computations in interneurons.

    High-resolution volumetric imaging constrains compartmental models to explore synaptic integration and temporal processing by cochlear nucleus globular bushy cells

    George A Spirou, Matthew Kersting ... Paul B Manis
    Volume electron-microscopic reconstructions of auditory brainstem neurons and their afferent synapses were used to develop a pipeline creating biophysically defined computational models with heterogenous inputs, revealing roles for subthreshold synapses to enhance temporal processing unique features of their dendrites.

    On demand expression control of endogenous genes with DExCon, DExogron and LUXon reveals differential dynamics of Rab11 family members

    Jakub Gemperle, Thomas S Harrison ... Patrick T Caswell
    DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.

    Coordinated regulation of gene expression in Plasmodium female gametocytes by two transcription factors

    Yuho Murata, Tsubasa Nishi ... Masao Yuda
    Sequential expression of two transcription factors that bind to five- and ten-base female-specific cis-acting elements, respectively, promotes differentiation of Plasmodium female gametocytes.

    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui, Ilya Prokin ... Hugues Berry
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.

    A paternal bias in germline mutation is widespread in amniotes and can arise independently of cell division numbers

    Marc de Manuel, Felix L Wu, Molly Przeworski
    A paternal bias in germline mutation is seen throughout amniotes and may be explained by sex differences in DNA damage and repair after primordial germ cell specification.

    Stimulation strength controls the rate of initiation but not the molecular organisation of TCR-induced signalling

    Claire Y Ma, John C Marioni ... Arianne C Richard
    The strength of TCR signalling determines the rate at which cells initiate a tightly coordinated signalling programme, without altering its organization.

    Resolving the origins of secretory products and anthelmintic responses in a human parasitic nematode at single-cell resolution

    Clair R Henthorn, Paul M Airs ... Mostafa Zamanian
    A single-cell gene expression atlas in a human parasitic nematode provides new insights into the distribution of anthelmintic targets and the origins of secretory molecules with diagnostic and therapeutic potential at the host–parasite interface.
