I entirely agree.
Research in rodents has enabled remarkable technical advances and deepened our understanding of brainstem circuits and general brain physiology.
However, only NHPs possess cognitive, visual, and motor faculties necessary to advance human-relevant systems neuroscience.

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.

Research in primate brains has been essential for the development of BCIs, ANNs. New funding and policy changes put future such advances at risk.

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…

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.
