Scientists from UCLA, Israel's Technion uncover brain's code for pronouncing vowels
Date:8/22/2012

Scientists at UCLA and the Technion, Israel's Institute of Technology, have unraveled how our brain cells encode the pronunciation of individual vowels in speech.

Published in the Aug. 21 edition of the journal Nature Communications, the discovery could lead to new technology that verbalizes the unspoken words of people paralyzed by injury or disease.

"We know that brain cells fire in a predictable way before we move our bodies," said Dr. Itzhak Fried, a professor of neurosurgery at the David Geffen School of Medicine at UCLA. "We hypothesized that neurons would also react differently when we pronounce specific sounds. If so, we may one day be able to decode these unique patterns of activity in the brain and translate them into speech."

Fried and the Technion's Ariel Tankus, formerly a postdoctoral researcher in Fried's lab at UCLA, followed 11 UCLA epilepsy patients who had electrodes implanted in their brains to pinpoint the origin of their seizures. The researchers recorded neuron activity as the patients uttered one of five vowels, or syllables containing the vowels.

With the Technion's Shy Shoham, the team studied how the neurons encoded vowel articulation at both the single-cell and collective level. The scientists found two areas the superior temporal gyrus and a region in the medial frontal lobe that housed neurons related to speech and attuned to vowels. The encoding in these sites, however, unfolded very differently.

Neurons in the superior temporal gyrus responded to all vowels, although at different rates of firing. In contrast, neurons that fired exclusively for only one or two vowels were located in the medial frontal region.

"Single-neuron activity in the medial frontal lobe corresponded to the encoding of specific vowels," Fried said. "The neuron would fire only when a particular vowel was spoken, but not other vowels."

At the collective level, neurons' encodin
