Dutch primate center awaits October animal research debate

Science is forging ahead at the Biomedical Primate Research Centre in the Netherlands, following a reversal of last year’s mandate to phase out primate studies. But researchers aren’t sure how long the reprieve will last.

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.

Govern neurodata by how it’s used, not where it’s from

New neurodata laws will shape how researchers gather, share and reuse brain data. A use-based governance protects basic researchers and those whose data are being used, without freezing science.
