to kind of have a convergent theory on this.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

It's still to be determined.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

There's still a lot of work, I think, that needs to be done.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

But it's certainly suggestive that there's pretty profound changes in brain activity and brain connectivity after.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

And what we've found to be really interesting

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

is the antidepressant effects of psilocybin have a particular connectivity change that we also see with our TMS approaches, right?

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

And it's this connectivity between the subgenual anterior cingulate and the default mode network.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

And so when we do this effective Stanford neuromodulation therapy stimulation, we see a down regulation, the connectivity between the negatively valenced mood state in the case of depressed individuals and the self-representation of the brain.

Huberman Lab

And you see that same connectivity change occur post-psilocybin, you know, suggesting there's a convergent mechanism.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

And it makes sense, right?

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

You've kind of got an over-connected, negatively valenced system, conflict system that's kind of

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

kind of attached on to the self-representation and people feel stuck, right?

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

And then when you do whatever you do that's effective, it unpairs those two systems.

Huberman Lab

Ibogaine is one of the

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

alkaloids that you can extract from an iboga tree root bark that's typically growing in the country of Gabon, Africa.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

So what individuals taking Ibogaine will say is that open eyes, they don't see anything, but closed eyes, they'll go back through and re-experience earlier life

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

memories and they will be able to experience it from a place of empathy not only for themselves but from others and kind of a detached empathy and being able to see this as almost a third party even though they were there

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

Ibogaine is in no way a recreational substance.

Huberman Lab
Essentials: Psychedelics & Neurostimulation for Brain Rewiring | Dr. Nolan Williams

You're essentially having this what they call a life review.

Huberman Lab

They also call it 10 years of psychotherapy in a night.
