really nice and well done meta-analyses and review here...highly recommended!
Can humans & animals really use internal maps to take shortcuts?
Tolman famously said yes - based largely on his Sunburst maze.
Our new review & meta-analysis suggests evidence is far weaker than you might think.

Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting
In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze...

With some trepidation, I'm putting this out into the world:

It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.
My hope is that this will be a living document, continuously improved as I get feedback.

They developed a groundbreaking blood test, called PAC-MANN. This new test can find pancreatic cancer in just 45 minutes, even in its earliest stages.

Does the hippocampus play a time-limited or perpetual role in spatial memory?
In naturalistic tasks, the hippocampus is NOT necessary for gross representations of large-scale environments. But it plays a long-lasting role in memory for local layouts and details.
