Bridging the gap between presynaptic hair cell function and neural sound encoding

Authors Jaime Tobón LM, Moser T Journal eLife Citation Elife. 2024 Dec 24;12:RP93749. Abstract Neural diversity can expand the encoding capacity of a circuitry. A striking example of diverse structure and function is presented by the afferent synapses between inner hair cells (IHCs) and spiral ganglion neurons (SGNs) in the

CaBP1 and 2 enable sustained CaV1.3 calcium currents and synaptic transmission in inner hair cells

Authors Oestreicher D, Chepurwar S, Kusch K, Rankovic V, Jung S, Strenzke N, Pangrsic T Journal eLife Citation Elife. 2024 Dec 24;13:RP93646. Abstract To encode continuous sound stimuli, the inner hair cell (IHC) ribbon synapses utilize calcium-binding proteins (CaBPs), which reduce the inactivation of their CaV1.3 calcium channels. Mutations in

Accelerated spike-triggered non-negative matrix factorization reveals coordinated ganglion cell subunit mosaics in the primate retina

Authors Zapp SJ, Khani MH, Schreyer HM, Sridhar S, Ramakrishna V, Krueppel S, Mietsch M, Protti DA, Karamanlis D, Gollisch T Journal eLife Citation eLife13:RP99945. Abstract A standard circuit motif in sensory systems is the pooling of sensory information from an upstream neuronal layer. A downstream neuron thereby collects signals

Stochastic tug-of-war among sarcomeres mediates cardiomyocyte response to environmental stiffness

Authors Haertter D, Hauke L, Driehorst T, Nishi K, Zimmermann WH, Schmidt CF Journal eLife Citation eLife 13:RP97321. Abstract Cardiac muscle function emerges from the coordinated contraction of sarcomeres in cardiomyocytes. Sarcomere dynamics are usually inferred from whole-cell or myofibril observations, assuming synchronized, uniform behavior. Here, we investigated how different

Establishing synthetic ribbon-type active zones in a heterologous expression system

Authors Kapoor R, Schwenzer N, Dresbach T, Lehnart S, Moser T Journal eLife Citation eLife 13:RP98254. Abstract Encoding of several sensory modalities into neural signals is mediated by ribbon synapses. The synaptic ribbon tethers synaptic vesicles at the presynaptic active zone (AZ) and might act as a super-scaffold organizing AZ

Intracellular mechanical fingerprint reveals cell type specific mechanical tuning

Authors Muenker TM, Vos BE, Betz T Journal eLife Citation eLife13:RP97416. Abstract Living cells are complex entities that perform many different complex tasks with astonishing robustness. While the direct dependence of biological processes on controlled protein expression is well established, we only begin to understand how intracellular mechanical characteristics guide

Boosting of neural circuit chaos at the onset of collective oscillations

Authors Palmigiano A, Engelken R, Wolf F Journal eLife Citation eLife 12:RP90378. Abstract Neuronal spiking activity in cortical circuits is often temporally structured by collective rhythms. Rhythmic activity has been hypothesized to regulate temporal coding and to mediate the flexible routing of information flow across the cortex. Spiking neuronal circuits,

Munc13 supports fusogenicity of non-docked vesicles at synapses with disrupted active zones

Authors Tan C, de Nola G, Qiao C, Imig C, Born RT, Brose N, Kaeser PS Journal eLife Citation eLife 11:e79077. Abstract Active zones consist of protein scaffolds that are tightly attached to the presynaptic plasma membrane. They dock and prime synaptic vesicles, couple them to voltage-gated Ca2+ channels, and
