Beyond Correlation versus Causation: Multi-brain Neuroscience Needs Explanation

Published on March 20, 2021

Recent advances in brain sciences have enabled the co-recording of multiple interacting brains (i.e., hyperscanning [1]). This technique has led to the discovery of inter-brain synchrony (IBS) between people involved in social and interactive scenarios. In a recent article, Novembre and Iannetti argued that studies using hyperscanning to understand social behaviors are crucial but limited to correlational analysis [2]. They further developed the idea that the causal role of IBS can only be apprehended through multi-brain stimulation (MBS).
