How new technologies can bring primatologists and systems neuroscientists together

The two groups study the same behavioral phenomena yet rarely interact or read each other's work—a mutual blind spot that weakens both fields. New technologies offer a chance to bring them together.

This paper changed my life: A first glimpse into the ‘middle’ of brain processing

Work by Jeffrey Moran and Robert Desimone showed that monkeys could focus their attention on different stimuli in their visual field without shifting their gaze. Their work marked a key milestone in the emergence of cognitive neuroscience.

What if nonhuman primate research goes away?

As the U.S. government takes steps to stop using nonhuman primates in research, The Transmitter investigates what that shift could mean for neuroscience.

U.S. national primate research centers face an uncertain future

The facilities were meant to last 100 years. Four decades shy of that mark, amid flatlined funds and mounting political pressure, their directors are trying to find a path forward.

Oregon primate research center to downsize monkey colony, pivot to non-animal models

The center’s host university had been negotiating with the federal government about converting the center into an animal sanctuary. A new plan, approved today, preserves some of the center’s nonhuman primate studies.

Cooperating marmosets extend decision-making model of the brain

When a pair of marmosets works together to earn some marshmallow fluff, one of them decides to act only after its brain accumulates enough evidence about what the other is doing, new work shows.

This paper changed my life: Erin Calipari ponders the nuances of rewarding and aversive stimuli

A 1960s study by Kelleher and Morse found that lever pressing in squirrel monkeys depended not on whether they received a reward or shock, but on the rules of the task. This taught Calipari to think deeply about factors that influence how behavior is generated and maintained.
