Welcome to the website of Elkan Akyürek, Professor of Cognitive Neuroscience at the Department of Experimental Psychology, University of Groningen, The Netherlands.
You can also find me on Twitter.
• One more preprint! Ahmet’s paper on the effects of ingesting GABA on attention and working memory has been posted to bioRxiv. Link here.
• We have a new preprint on bioRxiv, on the concurrent maintenance of both veridical and transformed working memory representations. This one has certainly taken its sweet time, but I think the result was worth it. As always, the link is in the Publications section.
• Gülşen’s second first-authored paper, on object benefits for features in working memory has just been accepted by Psychological Research. You can find the accepted manuscript in the Publications section!
• Funded by the CSC, Mingmin Zhang has joined the team. Welcome aboard!
• A new preprint on the adaptive nature of working memory encoding speed has been added to the Publications section. Work by Joost, Hedderik, and me.
• Another preprint has been added: In her very first manuscript, Shuyao looked into which model of working memory performance would fit best to attentional blink data. Have a look in the Publications section.
• Ivory’s first paper on concealed information detection was just accepted by Psychophysiology; well done Ivory! As always, you can find it in the Publications section.
• I very much enjoyed our working memory “Engram” meeting, and it ended on a particularly festive note with Aytaç winning the Poster Prize, together with Muhammet Sahan!
• On May 30-31st, as part of our NWO-funded ORA project, we are hosting an expert meeting on the cognitive neuroscience of working memory. The meeting will take place in Groningen, but all the talks will be livestreamed via our meeting website. We have some of the very best in the field on the program, so make sure to check it out!
• I am now also on Twitter (@elkanakyurek), so follow me there for more updates and retweets.
• We attended the excellent NVP
Winter Spring Conference again! From left to right: Güven, Gülşen, Joost, Sophia, Aytaç, Yining, Robbert, Yuanyuan, Elkan, Shuyao, and Ahmet.
• Michael’s excellent PhD Thesis has won the BCN Dissertation Award of 2020-2021. Congrats! It was well-deserved, in my only-slightly-biased opinion!
• I added a new preprint to the Publications section. It is a rebuttal to a paper by Barbosa, Lozano-Soldevilla, and Compte (2021, PLoS Biology), in which they present a critique of our paper on hidden brain states underlying working memory (2017, Nature Neuroscience).
• Congrats to Ahmet for just getting his first paper on the acute effects of cocoa flavanols on working memory accepted for publication in the European Journal of Nutrition!
• No fewer than three new team members have started in my lab this month: Robbert as a postdoc on the Police and Science project, Sophia as a PhD student funded by the Faculty PhD Fund, and Yuanyuan as a PhD student funded by the Chinese Scholarship Council. Welcome to all!
• The “Nothing But The Truth” symposium on truth and trust in science is coming up on the 1st of November. Organized by the BCN Research School, the symposium will feature plenary talks by John Ioannidis, Eric-Jan Wagenmakers, Heather Douglas and Hanneke Hulst, as well as several interactive workshops. Worth taking a look at, here!
• Our paper on the two faces of conscious awareness during the attentional blink has just been accepted for publication in the Journal of Experimental Psychology: General. I am happy to see the hard work of first author Aytaç thus rewarded, and to see Sophia publish her first paper, before she even formally started her PhD! Check out our preprint on bioRxiv to see what it is all about.
• The postdoctoral vacancy for the Police project is live! If you are interested in hidden knowledge detection, and if you are about to finish your PhD, or just did, take a look here. *expired*
• We have recently revised our original preprint from 2019 on conscious awareness during the attentional blink. As before, the new revision can be found on bioRxiv.
• A new preprint is available from the Publications section. It is the first paper by Ivory, which features some promising results on using pupillometry to detect concealed identity information.
• Another new member of the lab is incoming! The Faculty PhD Fund has selected the research proposal of Sophia Wilhelm, a BCN master student, for funding. Her project will be co-supervised by Robbert Havekes at the Groningen Institute for Evolutionary Life Sciences (GELIFES).
• Exciting times ahead: My research proposal on a new method for hidden knowledge detection in photo lineups was funded in the Politie en Wetenschap (“Police and Science”) research program. I will soon start recruiting a new postdoctoral researcher!
• Today Michael Wolff successfully defended his PhD Thesis at the University of Groningen, and received his doctorate degree with the distinction Cum Laude! Congratulations once more on this incredible achievement!

• I just heard that our manuscript “A functional spiking-neuron model of activity-silent working memory in humans based on calcium-mediated short-term synaptic plasticity” was accepted for publication by PLOS Computational Biology. Many thanks to my co-authors Matthijs Pals, Terrence Stewart, and Jelmer Borst!
• Acta Psychologica just accepted Gülşen’s first paper on “Adaptive event integration in the missing element task” for publication. Spoiler alert: It’s not very likely!
• Off to a good start of the new year: Michael’s paper “Drifting codes within a stable coding scheme for working memory” has been accepted for publication in PLOS Biology! You can still find the preprint on bioRxiv.
• We attended the NVP Winter Conference with pretty much the whole team again. From left to right: Güven, Ahmet, Shuyao, Elkan, Yining, Aytaç, Joost, and Gülşen. Happy holidays!
• The Journal of Neuroscience has accepted our paper on “Unimodal and bimodal access to sensory working memories by auditory and visual impulses” for publication. Nice! If you’re curious, the preprint remains publicly available on bioRxiv, here.
• Yet another bioRxiv preprint has been added to the Publications section. This one resulted from a collaboration with Jelmer Borst and features a spiking-neuron model of activity-silent working memory.
• Jefta Saija just successfully defended his PhD thesis. Well done and congratulations dr. Saija!
• Funded by a grant from the Chinese Scholarship Council, Shuyao Wang has just joined the team. Welcome!
