Memory Traces Observed in Vitro

It's less than implanting and reading a memory in vitro, but researchers were able to tell most of the time based on output which dentate neurons were being directy stimuated. Probably not now, but at some point, we're going to have to start asking hard questions about what structures necessarily produce consciousness (whether in vivo, vitro, or computationally), because then this work takes on a moral dimension.
