SALEM, Ore. (KOIN) — A Salem non-profit, Oregon Cryonics, is freezing human brains for future use.

It is one of only four facilities around the world. Three are in the U.S. and the other is in Russia. The Salem location is run by Dr. Jordan Sparks.

“Cryonics is the preservation of the brain in liquid nitrogen. The goal is to preserve the intricate 3D connectors between all the neurons. And the goal is to hopefully revive that person,” Sparks tells KOIN 6 News.

Cryonics is considered controversial, but Sparks says the hope is there. He envisions a future human or digital self in the next hundred years.

“We can see a clear pathway from here to how somebody might be revived. If we don’t do preservation, there’s zero chance for survival,” says Sparks. “We have electron micro-graphs showing good structured preservation and scientists around the world are currently mapping out neuro-connectors.”

More than 250 people have been frozen and another 2-to-3,000 have the same plans for their death, including Mathew Sullivan. Sullivan also convinced his dad to get frozen.

“I guess for me it’ll be the ultimate lottery ticket to see the future,” Sullivan says, who is also the Operations Manager for the facility.

He knows people are skeptical. “For some it’s radical but so were the Wright brothers hanging out in the garage trying to invent flight. So until it happens, until people see it demonstrated, then it probably will remain controversial.”

The procedure cost about $100,000. Life insurance does cover it.
