What Andrew Huberman has said about Neuroplasticity

Huberman said the adult brain changes in response to focused attention and error signals, not passive experience.

“The brain of the adult does not change just because of passive experience”

Huberman said the frustration of failing at a task is the signal that opens the door to learning.

“that frustration is the first gate of learning opening”

Huberman cited studies showing a phone in the room depletes cognitive resources even when focus is maintained.

“the amount of cognitive resources that you need in order to maintain focus is much higher and it robs it from your creative and problem-solving ability”

Huberman argues that clinical and everyday outcomes matter more than brain imaging changes after plasticity interventions.

“If the inter mid cingulate cortex or the posterior insula gets 10 thicker great but if you're not making better decisions like Frankly, who gives a shit, right?”

Huberman says raising BDNF through exercise alone does not produce plasticity without directed learning and precisely timed neural firing.

“You could quadruple the amount of circulating BDNF in your brain. nothing's going to change. I know this for a fact because for years I studied neuroplasticity. You need precisely timed neural firing pre- and post-synaptically”
