Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, Volume 309, Issue 4, Page 912-929, April 2026.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

A Rare Case of Diffuse Extra‐Cranial Schwannomatosis of the Trunk and Limbs

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Schwannomas are benign peripheral nerve sheath tumors (PNSTs) arising from myelin sheaths, with schwannomatosis characterized by multiple lesions without neurofibromatosis type 1 (NF1) or type 2 (NF2) stigmata. Malignant transformation is rare but documented.

Little Known Facts, Controversies and Misconceptions About Cranial Motor Nuclei (and a New Classification for All Motoneurons, Cranial, and Spinal)

Journal of Comparative Neurology, Volume 534, Issue 4, April 2026.
ABSTRACT Cranial nerves represent a notoriously complex province of the neuroanatomical landscape of the vertebrates. Here, we offer a selection of the anatomic, genetic, and developmental features of their efferent component that are often misrepresented, ignored or controversial, as a complement to more exhaustive treatments of the subject.
