    discusses many more things those findings tell us, but I particularly love his last sentence: Whether in seeing or imagining objects, our brains begin to construct what we “see” before the mind’s eye from basic visual features and with the help of what we know.

    Indeed, we found that the N1 component, associated with putting lower level features together as a meaningful configuration was delayed in imagery compared to perception and reduced when imagery failed. So building a stable representation seems to be what's hard in imagery.

    Knowing more about those objects didn't only change brain activity, but also made successful imagery more likely and faster. But clearly, there must be differences, right? I mean, perception is clearly easier than imagery.

    Importantly, we made sure that people don't know beforehand what we'll ask them to do, so they don't prepare to imagine things and never showed them the whole thing we wanted them to potentially imagine. We even asked them to do something else in between to reset visual activity.

    So we used a trick that's worked before in perception: We varied how much people know about the objects they see or imagine. In perception that modulates early visual processing (P1 for EEG aficionados) and we checked whether that happens in imagery as well. It does!

    How did we find out? So first we had to solve a hard problem: Imagery and Perception have totally different visual inputs, that obviously lead to differences in brain activity that will mask shared mechanisms. That is, we can't just compare them.

    How does mental imagery work and how does it differ from perception? , I, Johannes Rost, Werner Sommer and Rasha Abdel Rahman looked into this. td;dr imagery =/= just perception in reverse; both are active, constructive processes, sharing surprisingly early mechanisms

    Time course and shared neurocognitive mechanisms of mental imagery and visual perception

    Looks like they missed my twitter handle... Gives me an opportunity to retweet and thank and for their awesome responses to and discussion of our many detailed questions beyond the scope of their current really cool paper. That was fun!

    Bridging Motor and Cognitive Control: It’s About Time! , , & Romy Frömer highlight recent work revealing similarities in the algorithms that control our thoughts and movements ,

    I can’t unsee the dog... But, alas, if like me you start doubting your perception, google the painting.

    Have we considered that it's possible that Munch was just trying to paint a spaniel, but he was a bit shit, and then people got excited about it so he went along with it?

    I’ll present findings from a collaboration with and at Toronto, and obviously and from our very own and will be happy to discuss!

    What motivates us to invest cognitive effort and how do we translate these incentives into effort allocation and improved performance? (Pssst, with EEG) Care about fun GIFs, too? Come find me!

    Took me a while to compose this tweet. Finding the best among bad ideas just takes a while. Should have searched for the worst! 👨‍👧‍👧
