Understand & Improve Memory Using Science-Based Tools | Huberman Lab Essentials

About this video

In this Essentials episode, Huberman explains how memory works and how to improve it. He defines memory as a bias in which perceptions will be replayed in the future, and explains that only some perceived events get stamped in. Huberman describes repetition as strengthening chains of neurons, but focuses on adrenaline as the key signal: he explains that a sharp rise in adrenaline after learning reduces the repetitions needed, while the size of the rise relative to the prior hour or two is what matters. He warns that chronic elevation of adrenaline and cortisol impairs learning. Huberman also cites a study in which 13 minutes of daily meditation for eight weeks, but not four, improved attention and memory.
