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.

A study suggests that changes in an overactive immune system can contribute to autism-like behaviors in mice, and that in some cases, this activation can be related to what a developing fetus experiences in the womb.

In sports, on a game show, or just on the job, what causes people to choke when the stakes are high? A new study by researchers at Caltech suggests that when there are high financial incentives to succeed, people can become so afraid of losing their potentially lucrative reward that their performance suffers.

Nearly all motile bacteria can sense and respond to their surroundings through a process called chemotaxis, which begins with proteins known as chemoreceptors. Now researchers at Caltech have built the first model that depicts precisely how chemoreceptors and the proteins around them are structured at the sensing tip of bacteria. Because chemotaxis plays a critical role in the first steps of bacterial infection, a better understanding of the process could pave the way for the development of new, more effective antibiotics.
