Three Clocks Of Brain

Your brain is a time machine with three modes that control everything from instantaneous tasks like moving to maintaining long trains of thought and ultimately staying in synch with night and day.

Duke neuroscientists Warren Meck and Catalin Buhusi call the middle mode “interval timing.”

“To understand speech, I not only have to process the millisecond intervals involved in voice onset time, but also the duration of vowels and consonants,” Meck said Friday. “Also, to respond, I need to process the pacing of speech, to organize my thoughts coherently and to respond back to you in a timely manner.”

Theorists used to think interval timing was orchestrated by some sort of biological pacemaker that emitted timing pulses.
