A groundbreaking 3D-printed brain model, the Bioengineered Neural Network (BENN), developed by researchers at Postech in South Korea, is poised to revolutionize the understanding and early detection of neurodegenerative diseases such as Alzheimer’s and parkinson’s. This innovative model uniquely replicates both the structure and function of the human brain, opening new avenues for pre-clinical research and controlled testing of treatment strategies [[1]].
The Bioengineered Neural Network (BENN)
the BENN model stands out from traditional 2D cell cultures and organoids due to its three-dimensional architecture and realistic tissue compartmentalization. The model comprises distinct components that mimic the brain’s gray and white matter,featuring neuronal cell nuclei in the gray matter and aligned axons in the white matter. by applying electrical stimulation, researchers successfully guided axonal growth in specific directions, creating functional neural networks closely resembling natural signal pathways in the brain [[2]].
Did You Know? The global cost of Alzheimer’s and other dementias is estimated to be over $1.3 trillion in 2024, and is projected to increase to $2.8 trillion by 2030, according to the Alzheimer’s Association.
testing Clinical Relevance: Alcohol’s Impact
To assess the model’s clinical relevance, researchers investigated the effects of moderate alcohol consumption on brain function. For three weeks, the model was exposed daily to ethanol at concentrations mirroring social drinking. The results where significant: the gray matter showed elevated levels of Alzheimer’s-related proteins, such as amyloid beta and Tau. Furthermore, the white matter exhibited nerve fiber damage and swelling, along with demonstrably weakened neuronal signal transmission [[3]].
Professor Cho emphasized that the BENN model enables real-time monitoring of electrophysiological processes in the brain with high resolution. “We can now analyze region-specific neurotoxicity much more accurately, which brings us closer to effective prevention and treatment.” Professor Jang added, “This is an essential step towards unraveling the early mechanisms behind brain diseases.”
Pro Tip: Maintaining a healthy lifestyle, including regular exercise, a balanced diet, and cognitive stimulation, may help reduce the risk of developing Alzheimer’s disease.
Implications for Neuroscience and Precision Medicine
This technology offers significant potential not only for fundamental neurological research but also for developing personalized therapies and accurately predicting treatment outcomes. The BENN platform represents a promising addition to the tools available for pre-clinical research in neuroscience and precision medicine. The findings were published in the *International Journal of Extreme Manufacturing*.
Advancements in 3D Technology for Alzheimer’s Research
Earlier in 2025, the same Postech research team developed an innovative 3D model that accurately mimics the blood-brain barrier (BBB). Constructed from a bio-ink derived from pork-derived materials, this model spontaneously forms a double-layer structure that mirrors the human BBB. It provides an advanced platform for studying neuroinflammation and the BBB’s role in neurodegenerative diseases like Alzheimer’s.
In 2024, researchers at the University of Wisconsin-Madison pioneered a 3D bioprinting technique capable of printing functional human brain tissue. Unlike previous vertical printing methods, their approach involves horizontally printing stem cells in a gel medium, allowing the cells to self-organize into communicating neural networks. This model, containing both neurons and glial cells, presents new opportunities for studying neurological disorders such as Alzheimer’s and Parkinson’s. While the technology holds promise, the researchers acknowledge that fully simulating the human brain’s complexity remains a challenge.

How might these 3D brain models accelerate drug finding for Alzheimer’s disease? What ethical considerations should guide the growth and use of these advanced models?
The Growing Need for Alzheimer’s Research
Alzheimer’s disease is a progressive neurodegenerative disorder that gradually erodes memory and cognitive function. As the global population ages, the prevalence of Alzheimer’s is expected to rise substantially, placing an increasing burden on healthcare systems and families. The Alzheimer’s Association estimates that more than 6 million Americans are living with alzheimer’s in 2024. Finding effective treatments and preventative measures is a critical global health priority.
the Role of Brain Organoids in Research
Traditional methods of studying brain diseases,such as animal models,frequently enough fail to fully replicate the complexities of the human brain. Brain organoids, three-dimensional cell cultures that mimic the structure and function of the brain, offer a more accurate and ethical alternative. These models allow researchers to study disease mechanisms,test potential therapies,and develop personalized treatment strategies in a controlled laboratory environment [[4]].
