Theta rhythm: A Memory Clock

Video Description

Shortform link: https://shortform.com/artem My name is Artem, I'm a computational neuroscience student and researcher. In this video we talk about theta rhythm - a rhythmic pattern of brain activity (4-12 Hz), which is essential for memory encoding and retrieval.
