Hit a 95 mph baseball? Scientists pinpoint how we see it coming

How does San Francisco Giants slugger Pablo Sandoval swat a 95 mph fastball, or tennis icon Venus Williams see the oncoming ball, let alone return her sister Serena’s 120 mph serves? For the first time, vision scientists at the University of California, Berkeley, have pinpointed how the brain tracks fast-moving objects.

The discovery advances our understanding of how humans predict the trajectory of moving objects when it can take one-tenth of a second for the brain to process what the eye sees.

The nocebo effect: media reports may trigger symptoms of a disease

Media reports about substances that are supposedly hazardous to health may cause suggestible people to develop symptoms of a disease even though there is no objective reason for doing so. This is the conclusion of a study of the phenomenon known as electromagnetic hypersensitivity.

Those affected report experiencing certain symptoms on exposure to electromagnetic waves, such as those emitted by cell phones, and these take the form of physical reactions.

With the help of magnetic resonance imaging, it has been demonstrated that the regions of the brain responsible for pain processing are active in such cases.

The new study illustrates how media reports about health risks may trigger or amplify nocebo effects in some people.

Epilepsy Cured in Mice Using Brain Cells

Epilepsy that does not respond to drugs can be halted in adult mice by
transplanting a specific type of cell into the brain, UCSF researchers have discovered, raising hope that a similar treatment might work in severe forms of human epilepsy.

Cognitive abilities often regarded as unique to humans include humor, morality, symbolism, creativity, and preoccupation with the minds of others. In these compelling talks, emphasis is placed on the functional uniqueness of these attributes, as opposed to the anatomical uniqueness, and whether these attributes are indeed quantitatively or qualitatively unique to humans.

Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down -- like a radio dial or thermostat -- to correct dysfunction. A dramatic look at emerging techniques, in which a woman with Parkinson's instantly stops shaking and brain areas eroded by Alzheimer's are brought back to life.
