However, the
precise role of the cells, which are thought to serve as a switchboard for
routing signals through the brain's cortex, had remained unestablished, partly due to a dearth of methods to probe
how lab animals pay attention.
We'd practiced the 90 - mile race
route twice before today's main event, and with help from the factory team of Bill Rietow and John Townsend we had a good idea
how to maintain a
precise speed.
