What's a White Matter ‘Fiber’?

Clinical Anatomy, EarlyView.
ABSTRACT White matter anatomy is investigated using methods that operate at markedly different spatial scales and rely on distinct biological and physical principles. Nevertheless, the term “fiber” is routinely applied to the outputs of tract‐tracing studies, diffusion MRI tractography, and postmortem fiber dissection, often as though these entities ...

The Effect of Antecedent Topography on Complex Crater Formation

Geophysical Research Letters
Impact craters that form on every planetary body provide a record of planetary surface evolution. On heavily cratered surfaces, new craters that form often overlap antecedent craters, but it is unknown how the presence of antecedent craters alters impact

Connective tissue graft wall technique for mandibular Class II furcation defects: Two case reports

Clinical Advances in Periodontics, EarlyView.
Abstract Background Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to limited accessibility and the progressive interradicular attachment loss that compromises long‐term tooth stability. Deep periodontal pockets in molars and premolars often present as combined defects, including horizontal FI ...
