I study how the brain maps space - how this map is influenced by the environment & an animals's behaviour. Currently starting my own research group: the Neuroethology and Spatial Cognition lab @ University of Glasgow
Publication bias is bad, sure.
But has anyone studied publication bias in studies on publication bias?
(They have. There isn’t.)

Anecdote from Innis (1992)

To quell his anxiety, a group of Tryon's students conducted an Ocean's Eleven style operation to deconstruct and transport a huge rat maze from one building to another while a second group of students distracted him on an out of town trip.

In 1950s/60s "curiosity" was one of the theories proposed for exploration in animals.

The issue was that the theory (curiosity) could only be measured using the thing it was supposed to explain (exploration).

Makes sense to look at this in humans, where you can just ask them how curious they are!

Ethologists and neuroscientists: What is a theoretical ethology paper that has shaped the way you think about behaviour? Here I'm not thinking experimental papers with a point, or even tools that are developed to prove a point - purely theoretical, making conceptual, general points.

Unfortunately it overlooks our rodent place cell results in 3D:

Quite a nice paper/model.

I really like that it doesn't explain place cells in a vacuum - it incorporates place/boundary/pbject/grid cells into a holistic representation of space that can be used for planning.

Definitely check it out.
We are extremely grateful to Brad Pfeiffer and David Foster for sharing their data to enable these results. And to Éléonore Duvelle, @roddy-grieves.bsky.social and @hugospiers.bsky.social who shared another amazing dataset for us to reanalyse. doi.org/10.25493/7NJ... 8/9
