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.

Action potentials propagating in axon bundles with bifurcating and terminating fibers cause strong and far-reaching extracellular potentials.

Analysis of iconic and gating currents of wild type and mutated BK channels reveals a strong inhibition of this channel by extracellular acidification and elucidates the underlying mechanism that is potentially applicable to other voltage-dependent cation channels.

Different cytoneme types require specific heparan sulfate proteoglycans (HSPGs) that are stratified within the extracellular matrix in Drosophila.

Automated segmentation of neurons and identification of synapses in electron micrographs is significantly improved by using simple modifications to chemical fixation protocols that preserve extracellular space in the brain.

Free, extracellular dispersal of Wnt proteins generates a long-range gradient during animal development and is required for signaling.

Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD⁺-binding receptors and provide direct evidence for extracellular NAD⁺ being a bona fide endogenous signaling molecule in plants.

Direct measurement of finely patterned mechanical properties in a native basement membrane demonstrate how force asymmetries arising from this extracellular matrix, rather than from cells, can precisely sculpt a tissue.

Many extracellular matrix proteins that are up-regulated during breast tumor progression enhance metastasis, and some are prognostic indicators of poor survival.

Biochemical fractionation of vesicle sub-populations and in vitro reconstitution studies reveal that Lupus La protein mediates the selective sorting of miR-122 into extracellular vesicles in vitro and in vivo.
