The hippocampus is not a library, it is a simulation engine.

HPC is known for storing maps of the environment but not so known for generating planned trajectories.

This paper proposes that recurrence in CA3 is crucial for planning.

Nature research paper: Vicarious body maps bridge vision and touch in the human brain

Vicarious body maps bridge vision and touch in the human brain - Nature
A mode of brain organization that connects visual and bodily reference frames may translate raw sensory impressions into more abstract formats that are useful for action, social cognition and semantic processing.

New work by Emily Oby et al. in Nature Neuroscience demonstrates that neural population activity in motor cortex follows fixed dynamical constraints: monkeys could not volitionally reorder or reverse latent trajectories during BCI control.

In the end, even basic brain connectivity is different between rodents and primates, with primates having more specialized, sparsely connected brain regions.

Research in primate brains has been essential for the development of brain-computer interfaces and artificial neural networks. New funding and policy changes put future such advances at risk, write Cory Miller, @movshon.bsky.social and Doris Tsao.

Fear, monkeys, and institutional courage
When news broke of an explosion inside Harvard’s neurobiology building early Saturday morning, every scientist who works with monkeys felt it—an involuntary jolt, a spike of cortisol, the silent thought: what if it had been us? Neither animals nor people were hurt, thankfully. It doesn’t appear to have been an attack. But it didn’t matter. For those of us who work with monkeys, the fear is always near the surface.
