Groups of neurons that keep time with extreme precision have been discovered in the primate brain by a team of researchers that includes Dezhe Jin, assistant professor of physics at Penn State University and two neuroscientists at the Massachusetts Institute of Technology. This research is the first time that precise time-keeping activities have been identified in recordings of neuron activity.
Sitting at a lab desk, more like a console than a table, Jane Smith intently grasps the space-age controls. A hint of perspiration crowns her forehead as the faint whine of a drill is replaced by the sound of slick-moving mechanical parts. She focuses on the deft hand movements needed to manipulate a threadlike glass pipette. Slowly it enters the shaved skull of her "anesthetized recording preparation" (in this case, a rat). Carefully she explores its brain cavity. She's hunting for certain cells, and she can hear them coming.
