You can’t buy a human brain the way you’d buy any other item. In the United States, federal law makes it illegal to sell human organs for transplant, and the brain falls squarely under that prohibition. But the question “how much does a brain cost?” has several real answers depending on what you actually mean: the price of brain tissue for research, the cost of preserving a brain after death, what brain surgery runs, or even what it costs your body just to keep your brain running every day.
Selling a Human Brain Is a Federal Crime
The National Organ Transplant Act of 1984 makes it illegal to buy, sell, or transfer any human organ for “valuable consideration” when the transfer is intended for transplantation. The law covers kidneys, hearts, lungs, skin, bone, and any other organ the Secretary of Health and Human Services designates, which includes the brain. Violating this law carries a fine of up to $50,000, up to five years in prison, or both.
The law does allow “reasonable payments” for the removal, transportation, processing, preservation, and storage of organs. It also permits reimbursing donors for travel, housing, and lost wages. But those exceptions exist for the organ donation system, not for commercial sales. There is no legal market price for a human brain in the U.S. or in any other country with comparable organ trafficking laws.
Brain Tissue for Research: £40 to £1,600 Per Sample
Researchers don’t buy whole brains. They request small tissue samples from brain banks, which collect donated brains after death, process them, and distribute specimens for scientific study. The UK Brain Banks Network publishes a detailed tariff schedule that gives a good picture of what these samples cost.
A half-gram piece of fresh frozen brain tissue runs about £41 (roughly $52) for academic researchers and £83 ($105) for commercial users. Preserved tissue from one or two brain regions costs the same. Larger preserved blocks cost £165 to £330 ($210 to $420). A single stained microscope slide of brain tissue costs as little as £13 ($17). At the high end, induced pluripotent stem cells derived from brain tissue cost £1,600 ($2,030) for academics and £3,200 ($4,060) for commercial buyers.
These fees cover the processing, storage, and quality control involved in preparing the samples. The brain tissue itself is donated. No one is paying for the organ; they’re paying for the labor and infrastructure that makes research possible.
Cryonic Brain Preservation: $80,000
If your interest is in preserving a brain after death in hopes of future revival, the most well-known option is Alcor Life Extension Foundation, which offers “neuropreservation,” the cryonic freezing of just the head and brain. The current out-of-pocket cost is $80,000. That fee covers standby services (a team that begins the preservation process as soon as you’re legally declared dead), the cryopreservation procedure itself, and indefinite long-term storage in liquid nitrogen.
Full-body cryopreservation at Alcor costs $220,000. Most members fund either option through life insurance policies. It’s worth noting that no cryonically preserved organism of any complexity has ever been revived. The science behind restoration remains entirely theoretical.
Brain Surgery Costs in the U.S.
Another way to think about the “cost” of a brain is what it takes to operate on one. Neurosurgery is among the most expensive categories of medical care. A 2024 study examining hospital price transparency for skull base tumor procedures found that stereotactic radiosurgery, a focused radiation treatment for brain tumors, was listed at $99,548 at one major academic medical center and $124,486 at another. Those are the published prices for a single procedure at just two hospitals that actually disclosed their rates.
The same study found that zero hospitals in their analysis published pricing for open microsurgical removal of skull base tumors, making it nearly impossible for patients to comparison shop. Costs for brain surgery vary enormously depending on the procedure, the hospital, the surgeon, and whether complications arise. A straightforward biopsy might cost tens of thousands of dollars, while a complex tumor removal with a long hospital stay can exceed $200,000 before insurance.
What It Costs Your Body to Run a Brain
Your brain makes up about 2% of your body weight, typically around three pounds. Despite its small size, it consumes roughly 20% of all the calories and oxygen your body uses. For someone eating a standard 2,000-calorie diet, that means the brain burns about 400 calories per day just to keep functioning. Most of that energy goes toward firing electrical signals between neurons and maintaining the chemical gradients that make those signals possible.
This energy demand is constant. Your brain doesn’t use significantly more calories when you’re solving a difficult problem versus watching television. The baseline cost of keeping roughly 86 billion neurons alive and communicating is what drives the bill. In evolutionary terms, this is an enormous investment. No other organ of comparable size demands anything close to that metabolic share, which is one reason large brains evolved only in species with reliable access to calorie-dense food.
Why a Brain Transplant Has No Price Tag
Brain transplants do not exist. No surgeon has ever performed one, and the procedure remains in the realm of theoretical discussion. A 2022 paper in Surgical Neurology International outlined the four major barriers: the brain’s blood drainage system is physically fused to the inner lining of the skull, making extraction without catastrophic damage essentially impossible; the major arteries and veins feeding the brain can’t be reconnected with current surgical techniques once the brain is removed; there’s no technology to functionally reattach the twelve pairs of cranial nerves; and severed spinal cords cannot be reconnected.
Beyond the mechanical challenges, there’s no established method to keep a brain alive during the time between removal from one body and placement in another. And even if every surgical hurdle were cleared, immune rejection would remain a serious concern unless the receiving body were a genetic clone. The paper’s authors argued that a full brain transplant is “achievable, at least theoretically,” but theory and practice are separated by decades of unsolved problems. Because no procedure exists, there is no cost to quote.
