UCLA imaging system could help reveal 'miscommunications' in autism, schizophrenia

Some disorders of the brain are obvious - the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.

Researchers decode words from brain signals in paralyzed people

In an early step toward letting severely paralyzed people speak with their thoughts, University of Utah researchers translated brain signals into words using two grids of 16 microelectrodes implanted beneath the skull but atop the brain. "We have been able to decode spoken words using only signals from the brain with a device that has promise for long-term use in paralyzed patients who cannot now speak," says Bradley Greger, an assistant professor of bioengineering.

Quorum sensing offers a dynamic approach to increase sensitivity to external signals

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial "genetic clocks" to blink in unison and engineered the bacterial genes to alter their blinking rates when environmental conditions change.
