1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

For nearly 150 years, textbooks have described dendritic morphology as optimized for efficient synaptic voltage transfer from spines to the soma, implemented as a tubular design respecting Rall's 3/2 rule for impedance matching at branch points. Here, we reveal that this view is an oversimplification. Using multiple high-resolution imaging techniques, we demonstrate that dendrites in cortical and hippocampal neurons exhibit nanoscale constrictions, termed dendritic shaft constrictions (DSCs), with diameters ranging from ∼100 to 500 nanometers in mice. We also identified DSCs in human hippocampal and cortical neurons. We provide theoretical and experimental lines of evidence that these constrictions effectively partition the dendrite into distinct electrical compartments, shaping dendritic integration of synaptic potentials.
