Bryan Johnson, a biohacker known for spending $2 million a year on anti-aging experiments, has conducted a self-experiment involving ketamine injections to track its effects on his brain. Using his custom-built $64 million brain-scanning technology, Kernel Flow, Johnson observed significant changes in his brain’s activity over a 15-day period.
Before taking ketamine, Johnson's brain followed stable and predictable activity patterns. However, after the injection, his brain’s connectivity became highly irregular, akin to rerouting air traffic to unexpected locations. He suggested this shift might temporarily unlock new cognitive pathways, but within three days, his brain gradually returned to its normal state.
While Johnson highlights potential insights into how ketamine alters brain function, experts warn of the drug’s risks. The American Addiction Centers and the NHS caution that ketamine use can lead to memory impairment, organ damage, and personality changes. His experiment only looked at short-term effects, leaving open questions about the long-term impact of such interventions. Johnson believes his findings could help refine how AI and brain tech are used to study drug effects and cognitive health.
