Radiolab
The Spark of Life

And like things hop on and off.

Radiolab
The Spark of Life

They're called kinesins and dinesins, but...

The Spark of Life

I'm going to stick with tram.

But so, you know, if the mitochondria are in close proximity to these railway tracks or these microtubules, the light that's being emitted could be absorbed by that microtubule and be propagated down that track.

Radiolab
The Spark of Life

Like a fiber optic cable.

Radiolab
The Spark of Life

And so what we're testing right now is a series of experiments to see if the microtubule is that biological fiber optic cable.

Radiolab
The Spark of Life

We are working on that currently right now, but we do have strong evidence to show that the light that's being generated from neural cells, your brain cells, they are not random, that they are tied to purposeful activity of those neurons.

Radiolab
The Spark of Life

Well, it's the same kind of question we can, what kind of information does electricity carry?

Radiolab
The Spark of Life

I don't know, Roshan.

Radiolab
The Spark of Life

I just ask the questions.

Radiolab
The Spark of Life

I'm not... No, no.

Radiolab

But the information in this case is that the fact that, you know, maybe the wavelength, the oscillations of these light, the fact that they could carry biological information itself would be meaningful because if you look into your brain, between your two brain cells or, you know, things that carry information from one part of your brain to the other, we call that the white matter or the axons.

Radiolab
The Spark of Life

The white matter we're starting to see can carry photons.

Radiolab
The Spark of Life

So maybe each of those bundles of nerves act like a fiber optic cable.

Radiolab
The Spark of Life

And the same fiber optic cable that we see in telecommunication, they carry pulses of light that we use to carry information.

Radiolab
The Spark of Life

Why can't our brain do that?
