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

According to the latest studies from the fly laboratory of Caltech biologist David Anderson, male fruit flies fight more than their female counterparts because they have special cells in their brains that promote fighting. These cells appear to be absent in the brains of female fruit flies.

Subjects were asked to observe the shifting value of a hypothetical financial asset and make predictions about whether it would go up or down, while simultaneously interacting with an "expert" who was also making predictions.

"Traditional research has studied autism as a genetic disorder and a disorder of the brain, but our work shows that gut bacteria may contribute to ASD-like symptoms in ways that were previously unappreciated," says Sarkis Mazmanian.

A group of researchers led by Caltech neuroscientist Ralph Adolphs has made the first recordings of the firings of single neurons in the brains of autistic individuals, and has found specific neurons in a region called the amygdala that show reduced processing of the eye region of faces.

Colin Camerer, a behavioral economist at the California Institute of Technology whose work integrates psychology with economics experiments to understand how people behave when making decisions, has been named a MacArthur Fellow and awarded a five-year, $625,000 "no strings attached" grant.

New neuroeconomic research at Caltech has found that the financial investors most likely to take a risk and fuel bubble markets are those with good "theory of mind" skills—those who are good at "putting themselves in others' shoes."

Researchers have used a well-known, noninvasive technique to electrically stimulate a specific region deep inside the brain, causing volunteers to judge faces as more attractive than before their brains were stimulated.

When offered spinach or a cookie, how do you decide which to eat? Do you go for the healthy choice or the tasty one? To study the science of decision making, researchers in the lab of Caltech neuroeconomist Antonio Rangel analyze what happens inside people's brains as they choose between various kinds of food. The researchers typically use functional magnetic resonance imaging (fMRI) to measure the changes in oxygen flow through the brain; these changes serve as proxies for spikes or dips in brain activity. Recently, however, investigators have started using a new technique that may better tease out how you choose between the spinach or the cookie—a decision that's often made in a fraction of a second.
