Caltech researchers have, for the first time, pinpointed areas of the brain—the inferior lateral prefrontal cortex and frontopolar cortex—that seem to serve as an “arbitrator” between two decision-making systems, weighing the reliability of the predictions each makes and then allocating control accordingly.

The National Institute of Mental Health has awarded a five-year, $9 million grant to a research group Caltech to study the neurobiology of social decision making.

The grant establishes a Silvio O. Conte Center for Neuroscience Research, where researchers will use electrophysiology and functional magnetic resonance imaging to investigate how humans make social decisions.

The frontal lobes are the largest part of the human brain, and damage to this area can result in profound impairments in reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at Caltech teamed up with researchers at the world's largest registry of brain-lesion patients. By mapping the brain lesions of these patients, the team was able to show that reasoning and behavioral control are dependent on different regions of the lobes than the areas called upon when making a decision.

When jurors consider shortening the prison sentences of convicted criminals, they use parts of the brain associated with sympathy and making moral judgments, according to new work by Caltech neuroeconomist Colin Camerer and colleagues. They found that the most lenient jurors show heightened levels of activity in a brain region associated with discomfort, pain, and imagining the pain that others feel.

Researchers from Caltech have isolated a very specific difference in how high-functioning people with autism think about other people, finding that—in actuality—they don’t tend to think about what others think of them at all.

When making decisions based on multiple interdependent factors—such as what combination of stocks and bonds to invest in—humans look at how the factors correlate with each other, according to a new study by researchers from Caltech and University College London.

The sky is gray, but you're not sure if the clouds will clear or rain will pour. Do you grab an umbrella when you go outside? Such decisions are filled with ambiguity, and we're faced with them daily. "Almost every decision has some ambiguity," says Kota Saito, an economist who develops empirical and mathematical models on how people make decisions—insight that can inform socioeconomic policy. This fall, he joins Caltech as an assistant professor and the newest faculty member of the Division of the Humanities and Social Sciences.

Choosing what to have for dinner, it turns out, is a complex neurological exercise. But, according to researchers from the California Institute of Technology (Caltech), it's one that can be influenced by a simple shifting of attention toward the healthy side of life. And that shift may provide strategies to help us all make healthier choices—not just in terms of the foods we eat, but in other areas, like whether or not we pick up a cigarette.

Artificial intelligence has been the inspiration for countless books and movies, as well as the aspiration of countless scientists and engineers. Researchers at Caltech have now taken a major step toward creating artificial intelligence—not in a robot or a silicon chip, but in a test tube. The researchers are the first to have made an artificial neural network out of DNA, creating a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can.

In many ways, life is like a computer. An organism's genome is the software that tells the cellular and molecular machinery—the hardware—what to do. But instead of electronic circuitry, life relies on biochemical circuitry—complex networks of reactions and pathways that enable organisms to function. Now, researchers at Caltech have built the most complex biochemical circuit ever created from scratch, made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip.

When a group of gamblers gather around a roulette table, individual players are likely to have different reasons for betting on certain numbers. Recently, researchers at the California Institute of Technology (Caltech) and Ireland's Trinity College Dublin hedged their bets—and came out winners—when they proposed that a certain region of the brain drives these different types of decision-making behaviors.
