“We found that each speech sound initiates a cascade of neurons firing in different places in the auditory cortex. These changes are time-stamped by the brain to allow the temporal sequence of the sound to be identified. The brain activity representing each phoneme changes over time. The researchers found that the brain continuously processes the three most recently heard speech sounds together, passing activity among neurons found in the auditory cortex to avoid a pile-up of information. The brain needs to be able to process phonemes both at high speed and in the order they were heard (otherwise “pit” could be mistaken as “tip”). The researchers focused in on activity that appeared in response to individual speech sounds, called phonemes, that help us tell words apart, such as the “p” and “t” sounds that separate “pip” from “pit”. Gwilliams and colleagues recorded the brain activity of 21 participants while they listened to audiobook recordings in their native English for two hours. If we can better understand how the brain tackles these speedy sequences, we might also better understand neurological diseases, like aphasia, that affect the brain’s ability to process speech. But human speech bursts forth in a wild torrent of varying speed, noise level and accent. The brain’s ability to process single sounds has been somewhat demystified by years of careful study. This allows the listener to know both the order and the identity of the sounds that someone is saying to correctly figure out what words the person is saying.” And each sound is time-stamped with how much time has gone by since it entered the ear. “We show how the brain achieves this feat: different sounds are responded to with different neural populations. “To understand speech, your brain needs to accurately interpret both the speech sounds’ identity and the order that they were uttered to correctly recognize the words being said,” explained Gwilliams in a press release. Laura Gwilliams, a postdoctoral fellow at the University of California, San Francisco. The new findings were published in the journal Nature Communications. This ability, in combination with discrete neuronal populations capable of identifying different types of sounds, explains how we perceive the “what” and “when” of speech. But our innate skill at decoding the complex and varied sounds we use to communicate remains something of a mystery to scientists studying the brain.Ī new research paper has provided some answers, showing that the brain “time-stamps” sounds arriving at the ear.
