Our paper about the hippocampal contributions to model-based planning and spatial memory in humans, is now out. What a journey! Particularly grateful for our incredible collaborators and the participants who made this study possible. @NeuroCellPress
Super thrilled to share our years of work on human replay with the world, now out in Cell @CellCellPress, https://www.cell.com/cell/fulltext/S0092-8674(19)30640-3 … with my amazing supervisors: @behrenstimb @zebkDotCom and Ray Dolan. @WCHN_UCL @MPC_CompPsych @OxfordWIN @DeepMindAI (1/16)
Decoding sequential replay with fMRI. Big congrats @nico_schuck who demonstrates the importance of sequential reactivation in the human hippocampus for nonspatial decision-making and establishes the feasibility of investigating such rapid signals with fMRI https://science.sciencemag.org/content/364/6447/eaaw5181 …
super thrilled, honored and frankly excited to say that our paper on hippocampal replay of non spatial task states has been published in @sciencemagazine today!! tldr:hippocampal replay cares about task states+might help OFC learn them. fun teamwork with the amazing @yael_niv
Preprint: Value-based framework for understanding cooperation. Starting from neuroeconomic models of decisions and proposing directions for research focusing on memory, attention and social interaction! https://psyarxiv.com/bkn3j w. @TessaShussmy @diegoareinero @jayvanbavel
Testing patients with hippocampal damage, @vikbladh et al. demonstrate that planning & place memory both rely on the hippocampus https://www.cell.com/neuron/fulltext/S0896-6273(19)30123-0 … Preview by Iigaya & O’Doherty https://www.cell.com/neuron/fulltext/S0896-6273(19)30384-8 …
"Hippocampus Is What Happens while You’re Busy Making Other Plans". But if you're not too busy making other plans you should check out Iigaya & O’Doherty's fantastic Preview of our recent paper exploring the role of the hippocampus in planning. @nathanieldaw @NeuroCellPress
A role for the medial temporal lobe subsystem in guiding prosociality: the effect of episodic processes on willingness to help others https://academic.oup.com/scan/advance-article/doi/10.1093/scan/nsz014/5365293 … "Our willingness to help may be guided, in part, by how easily we can construct imagined and remembered helping episodes"
A multi-echo multi-band fMRI protocol with 7T vs. 3T leads to 200-300% improvement in tSNR. This helps to uncover differences in VTA-seed FC between depressed patients & healthy controls. Very promising work by @JMurrough's group. https://www.biorxiv.org/content/early/2018/11/09/459479 …
san diego at last! fyi if you are also here and dont have plans for monday, @evanrussek and I are presenting at a great cross-species nanosymposium on Goal Directed Behavior. I’ll show fMRI data on Episodic Memory as a mechanism for Model-Based Planning.https://www.abstractsonline.com/pp8/#!/4649/session/727 …
Excited to share our new preprint with Marc Howard, "Predicting the future with multi-scale successor representations". Mathy, but we've tried to give intuitive explanations of equations. Would love to hear thoughts! https://www.biorxiv.org/content/early/2018/10/22/449470 …
Big Nature Neuroscience day for us: @marcelomattar's fab theory of place cell replay came out https://rdcu.be/9Pjq with a kind N&V from @john_widloski & David Foster http://goo.gl/FtdDE6 , and (coincidentally) a piece from me about how it all started https://rdcu.be/9Plt
Then, by measuring the consistency of human decisions across repeated sequences of rewards, we validated that most of learning noise is due to random variance rather than to systematic biases – in other words, a misfit of our RL model. 6/16
New insights concerning the exploration/exploitation trade-off using a paradigm inspired by @nathanieldaw 's 2006 paper in which we included a complete feedback condition to reduce the need for direct exploration
