What are "place cells"? They are a category of neurons, first discovered in the brain of rats, that activate only in specific locations in a given environment. Each place cell fires at a different location, together forming a sort of map (#CognitiveMap) of all the locations that we know.
Can anyone recommend a good online, 3D!, rat brain atlas? (Allen one is for mice)
Ideally where you can highlight several brain regions simultaneously…
#Hippocampus#Ripples - aren’t they the best? (with sound)
Notice how most of them show a positive deflection (positive Sharp-Wave) while the tetrode at the bottom right shows a negative SW, because it’s been moved past the CA1 cell layer!
(Data shown is from 16 #Tetrodes aimed at dorsal CA1, arranged in moveable bundles indicated by the colour) #NeuroRat#Neuroscience

Dear @adredish ,
as the #ThetaSequences expert - do you think theta sequences can be remote (and that, like replay, they have an initiation bias which explains why most of them are local), or that they are by nature local, constrained to stay around the rat's current position?
Or maybe the third option: they are local, but can extend to a remote place (perhaps like what you saw in Wikenheiser & Redish, 2015?
“ We show that rats can efficiently navigate or direct objects to arbitrary goal locations within a virtual reality arena solely by activating and sustaining appropriate hippocampal representations of remote places.”
