Wouldn’t you like to know? A mouse would
Mice seek information for curiosity’s sake—and their desire for knowledge versus a payout is represented distinctly in the brain, new findings suggest.

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.

‘What Is Intelligence?’: An excerpt
In his new book, published today, Blaise Agüera y Arcas examines the fundamental aspects of intelligence in biological and artificial systems. In this excerpt from Chapter 4, he examines temporal difference, a reinforcement learning algorithm.

‘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.

Vijay Namboodiri and Ali Mohebi on the evolving story of dopamine’s role in cognitive function
Researchers discuss the classic stories of dopamine’s role in learning, ongoing work linking it to a wide variety of cognitive functions, and recent research suggesting that dopamine may help us "look back" to discover the causes of events in the world.

Amid funding uncertainty, neuroscientists report a mix of cynicism, persistence
Two years into one of the most tumultuous tenures in U.S. federal funding, researchers outline how they are coping with ongoing changes and reflect on the impact these changes are having on the system more broadly.
