Cellular Composition of the Brain of a Northern Minke Whale

open access: yesJournal of Comparative Neurology, Volume 533, Issue 9, September 2025.
Avelino‐de‐Souza et al. show that the minke whale has 3.2 billion neurons in the cerebral cortex, as predicted for a generic cetartiodactyl species, which places it and other cetaceans between monkeys and great apes in a ranking of mammal and bird species by total numbers of neurons in the pallium/cerebral cortex.

Craniogenetic studies in Sus scrofa: With emphasis on the ‘orbitosphenoid’ problem

open access: yesThe Anatomical Record, Volume 308, Issue 7, Page 1931-1943, July 2025.
Abstract The orbitosphenoid is a skeletal element of the endocranium of extant mammals. However, it has also been described in many of their fossil ancestors. Craniogenetic studies show that it is composed of two types of bone: first, the cartilaginous ala orbitalis and parts of the trabecular plate are transformed by endochondral ossification; second,

Skin development in the gray short‐tailed opossum (Monodelphis domestica)—From skin respiration to thermoregulation

open access: yesJournal of Anatomy, Volume 247, Issue 1, Page 108-133, July 2025.
The skin development in the gray short‐tailed opossum (Monodelphis domestica) has been examined using histological, morphometric, and μCT methods. During a long period of postnatal development, the structural differentiation of the skin results in a functional shift from transcutaneous gas exchange to thermoregulation in later life. Abstract Marsupials
