A neuronal population has now been found that regulates two competing needs — hunger and pain. Urgent pain overrides hunger, but appetite-inducing neuronal activity dampens long-term pain responses to enable feeding.

The hallmark of intelligence is the ability to learn. As decades of research have shown, our brains exhibit a high degree of “plasticity,” meaning that neurons can rewire their connections in response to new stimuli. But researchers at Carnegie Mellon University and the University of Pittsburgh have recently discovered surprising constraints on our learning abilities.
