    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.

  10. 291

    Why neural foundation models work, and what they might-and might not-teach us about the brain

    Carola Städele, a self-proclaimed “tick magnet,” studies the arachnids’ sensory neurobiology—in other words, how these tiny parasites zero in on their next meal.

  25. 276

    Lack of reviewers threatens robustness of neuroscience literature

    Simple math suggests that small groups of scientists can significantly bias peer review.
