The dendritic spine vicinome: characterizing its crowding in the human brain with petavoxel electron microscopy

The paper characterizes the dendritic spine vicinome in the human brain using petavoxel electron microscopy, finding that cortical depth, not neuron polarity, affects neighbor number.

Orientation-invariant morphometry reveals a continuum of dendritic spine forms in layer II pyramidal neurons of the petavoxel human connectome

This paper develops an orientation-invariant morphometry framework to analyze dendritic spines and finds they form a continuum rather than distinct subtypes.

Rotating a petavoxel reconstruction exposes the viewing-angle bias inherent to Golgi-Cox and confocal dendritic-spine classification

The paper shows that dendritic spine shape classification varies with viewing angle, challenging traditional 2D methods like Golgi-Cox and confocal microscopy.
