  • White Matter

    Biomedical editor Emily Singer had a diffusion tensor scan, a variation of MRI that allows scientists to visualize the brain’s white matter, at UCLA. Neuroscientist Andrew Frew used brain imaging software from BrainLab to create these movies, highlighting different sections of white matter.

  • Brain Imaging and IQ

    Richard Haier, a psychologist and emeritus professor at the University of California, Irvine, explains how brain imaging is shedding light on intelligence.

  • Linda Avey and Anne Wojcicki

    Anne Wojcicki and Linda Avey, founders of the personal-genomics company 23andMe, talk about their goals for the company and the drive to personalize medicine.

  • The Brain Unveiled

    This video combines different types of brain imaging to visualize a brain tumor in a female patient. Superimposed on a picture of the patient’s head are black and white images generated from traditional magnetic resonance imaging (MRI) presented sequentially in three different axes: side to side, front to back, and top to bottom. The tumor is then shown in yellow in the left hemisphere of the brain. Scientists further analyzed the data collected from the MRI to map the network of nerve fibers in the brain, seen here as red, green, and purple fibers. Neurosurgeons use these maps during surgery to remove the tumor to avoid damaging fiber tracts that are linked to important brain functions.
