What’s happening mechanistically Earlier work shows that psilocin (the active metabolite of psilocybin) acts primarily as an agonist at 5-HT₂A serotonin receptors in the cortex.

bryan_johnson's tweet photo. First mushroom trip data is out: my brain activity.

Dose: 5 g dried Psilocybe cubensis (B+ strain)
Containing 24.9 mg psilocybin
Psilocybin longevity experiment.

What we see in the brain:

+ brain activity data mirror my subjective experience

+ strong decrease in my brain’s control center (prefrontal + premotor cortex)

+ strong increase in sensory, auditory and speech integration

+ higher entropic brain patterns: open, flexible, less predictable, exploratory

+ brain network patterns resembling a youthful state vs aged and rigid

Matching what I reported experiencing:

+ “felt like my consciousness was dialed up to 10/10.”

+ “I felt hyper aware and hyper alive.”

+ “I experienced sense of touch with awe.”

+ “my mind was insatiably curious and wanted to deploy its sensors into the world and discover all things.”

+ “My brain wanted to stare, study and marvel.”

+ “The flavor exploded in my mouth.”

+ “...restored my perception to youthful levels, returning them to factory settings and dissolving my aged numbness.”

Why this could matter for longevity:

+ In people aged 65-85, higher happiness was linked to a 22% reduced risk of all-cause mortality over 15 years.

+ A meta-analysis showed that optimism correlated with a 35% decrease in heart attacks and a 16% decrease in all-cause mortality.

+ Having a strong purpose in life is associated with a 17% reduction in both heart attacks and all-cause mortality.

+ In psychedelic medicine, treating depression with ketamine has been shown to reverse biological age by up to 3 years.

Together, these findings suggest a plausible mechanism by which psychedelics, including psilocybin, can prolong both health and lifespan by improving mental well-being and rewiring the brain to a more positive, creative, and curious state.

Time point 2 - 5 hrs post dose, end of trip

+ Intensified sensory and motor hyperconnectivity.

+ Continued increased connectivity in auditory and speech centers, with a relative restoration of connectivity to the speech understanding area.

+ Partial re-emergence of the prefrontal parietal coupling, while prefrontal context remains partially inhibited.

+ Partial re-emergence of connectivity in areas related to the default mode network.

Subjective Experience

+ Persistence: Patterns from the acute phase continue, including general prefrontal cortex inhibition, ongoing neuronal plasticity, and heightened senses.

+ Intensified connectivity: Increased connectivity is noted in the speech generation area and the somatic sensory association area.

+ DMN inhibition: The default mode network remains inhibited.

Idk about that. He stated that he was trying to facetime his girl to see if it was cool with her. He goes on to say that he made an executive decision lol im thinking there was a mistake made by an employee. That employee should prolly get fired ha but this guy just saw something labeled for a certain price and took advantage of it
