Brain-computer integration systems with high neural congruence and an allocentric distribution of agency can be described as having a hivemind-like user experience. 

Systems in the hivemind quadrant often harness brain sensing and stimulation technologies to facilitate brain-to-brain neural entrainment or amplify inter-brain synchrony.

The users of such systems form a decentralized network of minds, with each user being a loci of agency that contributes democratically to the gestalt brain activity of all users in the network. This produces a sense of phenomenological unity in the group, where in there is the sense that others in the collective are having very similar subjective experiences. 

PsiNet is one example of a hivemind system
