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.

Some dopamine neurons signal default behaviors to reinforce habits
Movement-sensing neurons that target the striatum influence a mouse’s choice of action by favoring routine.

‘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.

Reconstructing dopamine’s link to reward
The field is grappling with whether to modify the long-standing theory of reward prediction error—or abandon it entirely.

Dopamine and the need for alternative theories
Some experimental findings are inconsistent with the dominant model of reward prediction error, highlighting the need for alternative testable and falsifiable models for dopamine function.

Does a new theory of dopamine replace the classic model?
My answer would be no, but the model poses challenges that will sharpen our understanding of dopamine and learning.

Every neuroscience lab needs an ethicist
The ethics issues that arise in neuroscience research are usually novel, unresolved and understudied. Embedding ethicists in labs helps scientists navigate these challenges and develop strategies in real time to prevent harm.

Beyond glucose: The brain may feed itself
Myelin may serve as an energy reserve for the brain, according to recent findings, prompting neuroscientists to rethink how the brain stores, shares and protects energy.
