Which of these famous "spatial cell" type is better?

Well, which is your favourite anyway? Yes it's a silly question

PS: this is the lab where I did my PhD and I strongly recommend it - let me know if you have any questions!

#Introduction

The kids I grew up with knew I was "different", but my parents and school insisted I was normal. Now I've explored #Autism #Prosopagnosia #Alexithymia and #Aphantasia and have an idea what was going on, but then I thought everyone saw the world like I did, just coped better. I coped by becoming a #PluralSystem by age three when I realized my girl self would have to be hidden. After six "guy" IDs, I'm now back being that girl. Still running the system, but with more E and less T...

Age nine I was forced to wear #Bifocal #PlusLensTheory glasses every waking moment. Shattered my body sense and #CognitiveMap - https://www.psychoros.com/consumed-by-the-light/ Spent endless days of lonely boredom exploring the ~30° wedges of #SpatialViewCells and the flat dioramas between them. Now I'm rebuilding a 3D world around my body, where #HeadDirectionCells can have a single basis and #DorsalStream depth can pop out of the flat distance like content from a random dot stereogram.

Despite all that, I've been online since #ARPAnet and #DJNR, wrote the first magazine article with simultaneous code distribution (via 8" floppies in the post), coded fab robots to move 6" & 8" Silicon wafers, built my (almost) independent #SolarPV and #SolarThermal house (7K lines of C++ from 1998, 42 device outs), and evolved an audio system with bandwidth from DC to a half MHz. Helped raise four unique kids, as adult minds in young bodies. Still mystify most of the adults I encounter...

New review on the “spatial cells” across different species! Looks very interesting:
Neural mechanisms for spatial cognition across vertebrates
Vinepinsky & Segev 2023

Small but important comment: it is perfectly normal for place cells to have multiple #PlaceFields ! Only in very small environments (<80cm diameter) will you mostly see single-field place cells. The single field is probably more the exception than the rule in the natural world.
