The hippocampus as a ‘predictive map’ | DeepMind

In our new paper, in Nature Neuroscience, we apply a neuroscience lens to a longstanding mathematical theory from machine learning to provide new insights into the nature of learning and memory. Specifically, we propose that the area of the brain known as the hippocampus offers a unique solution to this problem by compactly summarising future events using what we call a “predictive map.”

Wired for habit

Research from MIT shows that habit formation in primates is driven by neurons that weigh the cost of a habit, as well as the reward. The research provides insights into neuropsychiatric disorders that involve problems with repetitive behavior, such as Parkinson’s disease, Huntington’s disease, obsessive-compulsive disorder, Tourette syndrome, and autism spectrum disorder.
