Syllables that oscillate in neuronal circuits

10 junio 2015

Speech, emitted or received, produces an electrical activity in neurons that neuroscientists measure in the form of «cortical oscillations.» To understand speech, as for other cognitive or sensory processes, the brain breaks down the information it receives to integrate it and give it a coherent meaning. But researchers could not confirm whether oscillations were signs of neuronal activity, or whether these oscillations played an active role in speech processing. Researchers reached such conclusions after having created a computerized model of neuronal microcircuits, which highlights the crucial role of neuronal oscillations to decode spoken language, independently of speakers’ pace or accent.
