I am SO excited to share that our paper 'Sensory strength distinguishes imagination from reality' is now published! It was a long process but I'm so happy with the result. With @smfleming.

Unrelatedly, I wonder, especially since the last decade or so, &apart from DMN's major hubs, are there any differences between DMN's subcomponents back then when the DMN related research was in its infancy, & now, especially for the areas which are often intermixed with the salience network/reality monitoring areas, eg parts of ACC? Any change in the conceptualisation of DMN subcomponents, or is the ongoing inconsistency in its methodology something that we just have to live with?
Eleanor Maguire has used optical pumpted magnetometers to show that when we recall events from our life or imagine future events the medial prefrontal cortex is activated before the hippocampus, and so ''drives' it. It is connected via the retrosplenial cortex (which then connects with the hippocampus).

Hasn't Hakwan Lau been saying fpr a long time that the prefrontal cortex acts as a reality monitor? And used signal detection theory to model it? Doesn't take way from an empirical demonstration that indeed signal strength is the critical variable.
