I cannot find the source right now, but the past 20 years has seen a marked shift from individual to ensemble brain imaging, as individual brain responses (and by extension our imaging data) do not fully reflect or capture our natural state that is often far less compartmentalised. It took some advocacy for the field to move towards multi-brain imaging, not the least due to its technical challenges. On a deeper level, I also think the prior discrepency stems from how we perceive the world as individuals rather than a collective, our research methods implicitly reflecting this bias.
