Neurolucida Helps Scientists Discover that Gorillas are Relevant in the Study of Alzheimer’s Disease

Cortical neurons containing tau termed neurofibrillary tangle seen in the human brain with Alzheimer's disease. The researchers used Neurolucida to count and chart similar neurons in the gorilla brain.

Humans and gorillas are approximately 98% identical on a genetic level, however there is little published research exploring Alzheimer’s disease pathology in gorillas. A new paper reports that gorillas display similarities in advanced age to humans  ̶  including the presence of Alzheimer’s disease precursors like amyloid-beta (Aβ) plaques and tau lesions.

The study, published in the Journal of Comparative Neurology, provides evidence of Alzheimer’s disease precursors in the western lowland gorilla. Their findings broaden the scientific community’s understanding of the aging brain of some our closest living relatives and offer new insights for Alzheimer’s disease research.
