Among the 58 projects funded in furtherance of President Obama's "Brain Research through Advancing Innovative Neurotechnology"—or BRAIN—Initiative are six projects either led or co-led by Caltech researchers.

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.

The brain needs its surroundings to be just right. That is, unlike some internal organs, such as the liver, which can process just about anything that comes its way, the brain needs to be protected and to have a chemical environment with the right balance of proteins, sugars, salts, and other metabolites.

Humans have a tendency to spontaneously synchronize their movements. For example, the footsteps of two friends walking together may synchronize, although neither individual is consciously aware that it is happening. Similarly, the clapping hands of an audience will naturally fall into synch. Although this type of synchronous body movement has been observed widely, its neurological mechanism and its role in social interactions remain obscure. A new study, led by cognitive neuroscientists at the California Institute of Technology (Caltech), has found that body-movement synchronization between two participants increases following a short session of cooperative training, suggesting that our ability to synchronize body movements is a measurable indicator of social interaction.

Viviana Gradinaru (BS '05) might one day be getting inside your head—but in a good way. An assistant professor of biology at Caltech, Gradinaru is trying to map out the brain's wiring diagrams. Gradinaru will discuss her work at 8:00 p.m. on Wednesday, December 5, in Caltech's Beckman Auditorium. Admission is free.

A team led by Colin Camerer and Shinsuke Shimojo has found a way to predict the severity of hindsight bias and has identified a technique that successfully reduces it.

Researchers at Caltech have found that people make speed-dating decisions based on a combination of two different factors that are related to activity in two distinct parts of the brain.

Almost everyone knows the feeling: you see a delicious piece of chocolate cake on the table, but as you grab your fork, you think twice. The cake is too fattening and unhealthy, you tell yourself. Maybe you should skip dessert. But the cake still beckons.

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.

By mapping the brain lesions of patients, neuroscientists at Caltech were 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.
