Caltech biologist Richard Andersen is working to incorporate a sense of touch into the neural prosthetics he has been helping develop for years—devices implanted in the brain that allow a paralyzed patient to manipulate a robotic arm.
Building on previous studies targeting the amygdala, a team of researchers has found that some brain cells recognize emotions based on the viewer's preconceptions rather than the true emotion being expressed.
Building on their prior work, a team of neuroscientists at Caltech now report that rare patients who are missing connections between the left and right sides of their brain show a strikingly high incidence of autism.
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.
