How to transform UMAP from a black box into a glass box: by using a special type of deep network, we can now compute exact linear equivalents that reveal which features drive each point's position in the embedding. @ArcadiaScience [1/8]

The hippocampus is one of the most studied brain areas because of its major role in fundamental brain functions including learning, memory, and spatial navigation. In a new #ScienceReview, researchers focus on the role of overlooked areas and circuits within the hippocampus.

Teamed up again with @SolteszLab to write about outside-the-box topics in the hippocampus - out now in @ScienceMagazine. Ever heard of the fasciola cinereum? Maybe you know about ripples, but not dentate spikes. We dive into these and other cool topics
science.org
Traditional views of hippocampal function are largely based on the canonical flow of information from the entorhinal cortex through the trisynaptic loop—comprising the dentate gyrus and cornu ammonis...

Compared to humans, non-human primates appear less able to mentally rearrange items to new, non-adjacent temporal positions. This study shows that macaques can learn to rearrange members of 5-object...
