Brain Entropy

Neuroscience

Randomness of brain activity.

Example: This is the core idea behind Carhart-Harris's "entropic brain" hypothesis — see our Default Mode Network entry above for how psychedelics are thought to raise it by collapsing that network's normal, low-entropy organization.

What is brain entropy?

Randomness of brain activity.

Why do researchers think psychedelics raise brain entropy?

It's the core idea behind Carhart-Harris's "entropic brain" hypothesis — psychedelics are thought to raise it by collapsing the default mode network's normal, low-entropy organization. See our Default Mode Network entry.
