Until recently, Zeki believed that without the area known as V1, the part of the brain that first receives input from the retina, conscious visual perception would be impossible. V1 is a sort of clearinghouse, a place where incoming signals are split up and sent to the sites where they can be processed. But one patient, a 38-year-old man whose V1 for one eye was wiped out in an automobile accident, is also quite clearly aware of motion seen by the "blind" eye even when the good eye is covered. "We find," says Zeki, "that he is consciously...
...York University Medical School neuroscientist Dr. Rodolfo Llins also thinks coordinated electrical signals give rise to consciousness, though his idea is subtly different from Crick and Koch's. Llinas believes that the firing of neurons is not just simultaneous but also coordinated. Using a highly sensitive device called a magnetoencephalograph, which indirectly measures the electric currents within the brain, Llinas measured the electrical response to external stimuli (he used musical tones). What he observed was a series of perfectly timed oscillations. Says Llinas: "The electrical signal says that a whole lot of cells must be jumping up and down...
...happy with Administration and congressional efforts to free her husband, who faces the death penalty on whatU.S. officials consider trumped-up espionage charges. But she said Mrs. Clinton, who plans to chair the United Nations International Woman's Conference in Beijing in September, would send the "wrong signal" if she made the trip.

I was crying with Captain Thomas Hanford when he flew over the Adriatic and heard O'Grady's radio signal. My heart was pounding along with Marine Sergeant Major Angel Castro's after the successful chopper rescue. I made the helicopter ride of a lifetime with Marines Paul Bruce and Michael Pevear. And finally, I too smelled the cypress and pine trees of the Dalmatian coast. It made me feel great. Joe Raymond...
Hours before the Fed announcement, the Commerce Department reported that its Index of Leading Indicators -- the chief forecasting gauge of future economic activity -- fell for a fourth straight month in May.
