Bexorg Keeps Donor Brains Partially Functional for Drug Tests, Sparking Reddit Backlash Over Consciousness Risks
3 articles · Updated · Notebookcheck.net · May 27
Bexorg is using its BrainEx system to keep brains from deceased human donors partially functional so it can test treatments for Alzheimer’s, Parkinson’s and ALS directly in human tissue.
Artificial fluids replace blood by delivering oxygen and clearing waste, while artificial lung and kidney support helps preserve metabolic activity long enough for researchers to measure drug effects.
Bexorg says the brains offer disease histories, genetics, environmental exposure and prior drug traces that animal models and cell cultures cannot match, potentially making screening more precise.
Critics argue the brains may be neither fully dead nor fully alive and warn that rudimentary perception could persist, even though Bexorg says coordinated electrical activity is largely absent and uses Propofol to suppress it.
Reddit users have cast the work as dystopian and questioned a for-profit company’s use of donated body parts, with some saying the project makes them reconsider organ or whole-body donation.
If donated brains are truly dead, why are they given anesthetics during drug trials?
To cure Alzheimer's, must we experiment on revived brains, blurring the line between life and death?
From Death to Data: Bexorg’s BrainEx and the New Era of Human Brain-Based Drug Discovery
Overview
Bexorg, founded by Yale neuroscientists, has transformed neurological drug discovery with its BrainEx platform. Building on research that restored cellular and metabolic activity in postmortem brains, BrainEx uses donated human brains to create a more accurate model for early drug testing. This breakthrough not only accelerates the development of treatments for diseases like Alzheimer’s and Parkinson’s but also opens new possibilities for brain recovery after stroke or trauma. By revealing a greater capacity for brain cell restoration than previously known, BrainEx addresses the limitations of traditional animal models and marks a major advance in human-focused neuroscience research.
