Predictive maps in rats and humans for spatial navigation

Highlights We tested humans, rats, and RL agents on a novel modular maze Humans and rats were remarkably similar in their choice of trajectories Both species were most similar to agents utilizing a SR Humans also displayed features of model-based planning in early trials Authors William de Cothi, Nils Nyberg, Eva-Maria Griesbauer, …,E ́ le onore Duvelle, Caswell…

How young animals learn to migrate

While advances in biologging have revealed many spectacular animal migrations, it remains poorly understood how young animals learn to migrate. Even in social species, it is unclear how migratory skills are transmitted from one generation to another and what implications this may have. Here we show that in Caspian terns Hydroprogne caspia family groups, genetic and foster…

Olfactory landmarks and path integration converge to form a cognitive spatial map

This paper on olfactory landmarks is interesting as it covers the idea that the distinctive smell of a place can help navigation by creating a new landmark for helping an animal navigate. The recognition of a spatial landmark by its sensory features poses a problem for neural circuits. Fischler-Ruiz, et al. show how this problem…

Modelling collective navigation via non-local communication

A recent paper called “Modelling collective navigation via non-local communication”has been published by S. T. Johnston(1) and K. J. Painter(2). They tell us that a group of individuals produce better navigational results thanindividuals which is why flocks of birds are more efficient than a solo migrant. TheRAF confirms this where they have found that a…
