Hi all! My first "neuro-focused" post 🧠​ has to be these beautiful #PlaceCells that I recorded in a #NeuroRat foraging for cocops in a rectangle. #Hippocampus

#NeuroForNewbies ⏬​(trying this out)

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.

@PessoaBrain this was in an elevated rectangle of about 1.2 m long (my current screening environment):

@PessoaBrain also if you meant “where” as in brain region: Hippocampal dorsal CA1, theoretically, although I haven’t done histology yet.

Ah CA1

@PessoaBrain you seem disappointed 😅​

No no, was just wondering where!
Btw, I know so little about hippocampus+ areas, really need to delve into it given my attempt to create dynamic fMRI human experiments with approach/avoidance navigation.
