Helicon enables helical indexing and 3D reconstruction from a single 2D image using linear regression and regularization techniques.

The paper validates helical symmetry parameters in EMDB by identifying and correcting inconsistencies between parameters and density maps.

The paper investigates cue-invariance in neural representations of visual patterns in macaque V1 and V2, finding that population geometry provides a more robust cue-invariant representation than individual neuron tuning.
