Mapping the connections between neurons could lead to a better understanding of the brain. Chemist Charles M. Lieber, biologist Venkatesh N. Murthy, and coworkers at Harvard University have used arrays of nanowire field-effect transistors to record electrical signals in fresh rat brain slices with up to 5-μm spatial resolution and sub-millisecond temporal resolution (Proc. Natl. Acad. Sci. USA, DOI: 10.1073/pnas.0914737107). Other methods for recording electrical signals in the brain such as . . .
