‘Understudied secret’ in brain dampens nicotine drive in mice

The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Newly found circuit through visual cortex powers first look at faces

The superior colliculus, an evolutionarily ancient brain area responsible for eye movements, responds to faces before the canonical face areas do, a study of macaque monkeys suggests.

Mind over metrics: How can we tell if two brains (or AI models) are alike?

The ability to record from large populations of neurons has triggered the development of myriad methods for comparing them. But we’re still grappling with how to convert measures of likeness into a better mechanistic understanding.

Mice playing, engaged in learning and memory: some of their brains are yellow, and some are red, matching a red and yellow legend that runs through the image to underscore both memory and learning.

This paper changed my life: A technical breakthrough for memory studies

In a 2007 Science paper, Mark Mayford and his colleagues found that some neurons activated during learning are also recruited during memory retrieval. Noelia Weisstaub shares how this study and others drove an era of great progress in tool development.
