At this risk of kvelling, in 2011 we published a paper (Buschman et al., 2011) showing independent visual working memory capacities in the right vs left visual hemifields.  We were told “no way” and “that’s impossible”.  Since then, a bunch of papers have supported this.  Here’s another one.

Wang et al used FMRI and found that brain networks primarily interact with ipsilateral, not contralateral networks.  Thus, the brain emphasizes processing within each hemisphere (visual hemifield) and minimizes across-hemisphere processing.
