Anyone knows of researchers that compare #Mice and #Rats behaviour (ideally in complex tasks)? It could be in #SpatialCognition but also in other fields. Papers that directly compare both species would also be great.

If you want to study #HippocampalReplay... Use ephys, not #CalciumImaging!!

(Calcium imaging doesn't detect single spikes well, but replay mostly involves single spikes)
#Neuroscience #SpatialCognition #Hippocampus

The #Tolman "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 #ComputationalModels 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.

Reading Mental exploration of future choices during immobility theta oscillations

If you've read it, will you let me know what you think?

The authors look at #ThetaSequences in a working memory task in a radial arm maze. They find theta during immobility (makes sense, e.g. we saw that in our two-goals task). They also find that theta sequences might preferentially represent the next goal (also makes sense, e.g. Hippocampal theta sequences reflect current goals)!

I have only done a quick reading so far, but am confused by a few points:

• the decoding is done on all cells (pyramidals and interneurons), shouldn't it be done on pyramidal or #PlaceCells only?
• 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 #Neuropixels are not the best to record from dCA1!

• 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)

• also, this study is very related to this other paper, which is not discussed or even cited ( ):
  Assembly Responses of Hippocampal CA1 Place Cells Predict Learned Behavior in Goal-Directed Spatial Tasks on the Radial Eight-Arm Maze #CsisvariLab

Let me know what you think!

With the current situation in the #US, several of my former colleagues there are looking for a #PostDocJob in #Europe, to do #BehaviouralNeuroscience or #ComputationalNeuroscience in #SpatialCognition (or adjacent).
Lots of hashtags I know..

Do you know a #EU or #UK #Neuroscience lab looking to hire a postdoc in these fields? Let me know and I'll pass it on to them!

Edit: adding #RodentResearch and #humanresearch for the species concerned (in this case)

The proceedings of the 14th International #SpaceSyntax symposium are now published, containing papers from scholars all around the world on topics such as #architecture #ArchitectureResearch #ComplexBuildings #Urbanism #UrbanMorphology #methodology #EvidenceBasedDesign #SpatialCognition and #SpaceUseBehaviours

For our next #NeuroESC #JournalClub I will read this paper from @jessetm :

Flexible decision-making is related to strategy learning, vicarious trial and error, and medial prefrontal rhythms during spatial set-shifting

get the PDF at: https://drive.google.com/file/d/1qmfyeNkOwe_R-tvCOc0uSq3AX2WkMt4I/view?usp=sharing

Anyone else interested? We could all pledge to read it and then discuss it here afterwards (Next Friday)

Yoo-hoo we received our new #SpikeGadgets order!!
It has all we need to do 128ch and 32ch wired or wireless recordings!!

For context this is in my new lab at the #UniversityOfGlasgow (apparently we might be the only ones in the UK to use SpikeGadgets ?!?!) with Roddy Grieves as PI! Our lab name is #NeuroeSC for #Neuroethology and #SpatialCognition
