Humans and animals use mental representations of the spatial structure of the world to
navigate. The classical view is that these representations take the form of Euclidean …

The prefrontal cortex (PFC) supports decision-making, goal tracking, and planning. Spatial
navigation is a behavior that taxes these cognitive processes, yet the role of the PFC in …

Much of our understanding of navigation comes from the study of individual species, often
with specific tasks tailored to those species. Here, we provide a novel experimental and …

Human decision-making is mainly driven by two fundamental learning processes: a slow,
deliberative, goal-directed model-based process that maps out the potential outcomes of all …

Recent advances in artificial intelligence (AI) and neuroscience are impressive. In AI, this
includes the development of computer programs that can beat a grandmaster at GO or …

Reinforcement learning (RL) models have been influential in characterizing human learning
and decision making, but few studies apply them to characterizing human spatial navigation …

The hippocampus has been firmly established as playing a crucial role in flexible navigation.
Recent evidence suggests that dorsal striatum may also play an important role in such goal …

Learning how to reach a reward over long series of actions is a remarkable capability of
humans, and potentially guided by multiple parallel learning modules. Current brain imaging …

European law now requires AI to be explainable in the context of adverse decisions affecting
the European Union (EU) citizens. At the same time, we expect increasing instances of AI …

The current study investigated how stress affects value-based decision-making during
spatial navigation and different types of learning underlying decisions. Eighty-two adult …
