Dynamic patterns of functional connectivity in the human brain underlie individual memory formation

A. T. Phan, W. Xie, et al.

This groundbreaking study by Audrey T. Phan and colleagues reveals the fascinating connection between rapid brain connectivity changes and episodic memory formation. It showcases how specific dynamic changes during learning are crucial for successful recall, potentially transforming our understanding of memory mechanisms.

Abstract
This study investigates how sub-second changes in brain connectivity relate to episodic memory formation using intracranial EEG data from 20 participants performing a paired associates verbal memory task. The researchers identified functional connections exhibiting strong correlations with consistent time delays. Successful memory formation involved dynamic sub-second connectivity changes specific to each word pair, patterns that were reinstated during successful retrieval. This directly links specific dynamic changes in brain connectivity to successful memory formation.
