El Duvelle NeuroThe <a href="https://neuromatch.social/tags/Tolman" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Tolman</a> "sunburst maze" results (from 1946) are often used to demonstrate shortcut ability in rats... but do they really? More on this later!For now, would you know of any <a href="https://neuromatch.social/tags/ComputationalModels" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ComputationalModels</a> that were tested in this protocol (whether they replicate the original results or not)? We know of a few (well... 4) but would like to make sure we are not missing any.<a href="https://neuromatch.social/tags/BehaviouralNeuroscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BehaviouralNeuroscience</a> <a href="https://neuromatch.social/tags/SpatialCognition" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SpatialCognition</a> <a href="https://neuromatch.social/tags/Shortcuts" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Shortcuts</a> <a href="https://neuromatch.social/tags/CognitiveMap" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CognitiveMap</a> <a href="https://neuromatch.social/tags/Neuroscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Neuroscience</a> (kind of)

El Duvelle Neuro<a href="https://neuromatch.social/tags/PlaceCells" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PlaceCells</a> often have elongated place fields next to an environment's boundaries. Is there any paper where this phenomenon is directly predicted by the <a href="https://neuromatch.social/tags/SuccessorRepresentation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SuccessorRepresentation</a> model of place cells? <a href="https://neuromatch.social/tags/SpatialCognition" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SpatialCognition</a> <a href="https://neuromatch.social/tags/Neuroscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Neuroscience</a> <a href="https://neuromatch.social/tags/Hippocampus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hippocampus</a>

They find theta during immobility (makes sense, e.g. we saw that in our <a href="https://elduvelle.github.io/ElDuvelle/status/1385701872376455172/" rel="nofollow noopener noreferrer" target="_blank">two-goals task</a>). They also find that theta sequences might preferentially represent the next goal (also makes sense, e.g. <a href="https://www.nature.com/articles/nn.3909" rel="nofollow noopener noreferrer" target="_blank">Hippocampal theta sequences reflect current goals</a>)! I have only done a quick reading so far, but am confused by a few points:<ul><li>the decoding is done on all cells (pyramidals and interneurons), shouldn't it be done on pyramidal or <a href="https://neuromatch.social/tags/PlaceCells" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PlaceCells</a> only?</li><li>the cell counts are quite low (often less than 40 pyrs) when I would have thought at least 50 place cells would be needed for this kind of maze. I guess that shows that <a href="https://neuromatch.social/tags/Neuropixels" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Neuropixels</a> are not the best to record from dCA1!</li><li>the decoded algorithm itself includes a ' position transition matrix' which seems like it would bias decoding towards realistic trajectories that the rat is about to do??? (but I probably missed something)</li><li>also, this study is very related to this other paper, which is not discussed or even cited (😕 ): <a href="https://www.cell.com/neuron/fulltext/S0896-6273(18)31006-7" rel="nofollow noopener noreferrer" target="_blank">Assembly Responses of Hippocampal CA1 Place Cells Predict Learned Behavior in Goal-Directed Spatial Tasks on the Radial Eight-Arm Maze</a> <a href="https://neuromatch.social/tags/CsisvariLab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CsisvariLab</a></li></ul>Let me know what you think!<a href="https://neuromatch.social/tags/LeutgebLab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LeutgebLab</a> <a href="https://neuromatch.social/tags/NeuroRat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NeuroRat</a> <a href="https://neuromatch.social/tags/Neuroscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Neuroscience</a> <a href="https://neuromatch.social/tags/SpatialCognition" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SpatialCognition</a>
