Article Synopsis
- Hypoxia may contribute to neurodegenerative changes in the brains of cetaceans, particularly in beaked whales, known for their deep diving behavior.
- Samples from nine toothed whales revealed that 67% showed signs of neurodegenerative markers like Aβ plaques and neurofibrillary tangles, resembling conditions seen in human neurodegenerative diseases.
- These findings suggest that despite their adaptations for deep diving, cetaceans might be at risk for brain damage due to repeated episodes of low oxygen.
Cetaceans greatly depend on their hearing system to perform many vital activities. The spiral ganglion is an essential component of the auditory pathway and can even be associated with injuries caused by anthropogenic noise. However, its anatomical location, characterized by surrounding bony structures, makes the anatomical and anatomopathological study of the spiral ganglion a difficult task.

Most probable CD, grouped as pathologic categories (PCs), was identified in 208/224 (92.8%) examined animals.
