Zeroing in on the brain's speech 'receiver'

06-20-2007 · EurekAlert!

A particular resonance pattern in the brain's auditory processing region appears to be key to its ability to discriminate speech, researchers have found. They found that the inherent rhythm of neural activity called "theta band" specifically reacts to spoken sentences by changing its phase. The researchers also noted that the natural oscillation of this frequency provides further evidence that the brain samples speech segments about the length of a syllable.

Making sense of the world through a cochlear implant
03-13-2007 · EurekAlert!
Scientists at University College London and Imperial College London have shown how the brain makes sense of speech in a noisy environment, such as a pub or in a crowd. The research suggests that various regions of the brain work together to make sense of what it hears, but that when the speech is completely incomprehensible, the brain appears to give up trying.

Left brain helps hear through the noise
11-14-2007 · EurekAlert!
Our brain is very good at picking up speech even in a noisy room, an adaptation essential for holding a conversation at a cocktail party, and now we are beginning to understand the neural interactions that underlie this ability. An international research team reports today, in the online open-access journal BMC Biology, how investigations using neuroimaging have revealed that the brain's left hemisphere helps discern the signal from the noise.

Where the brain makes sense of speech
12-19-2007 · EurekAlert!
Researchers have identified regions of the brain where speech sounds are perceived as having abstract meaning, rather than as just a stream of sensory input. They said their identification of the regions demonstrates that the understanding of speech does not just emerge from lower-level processing of speech sounds, but involves a specialized perceptual region.Steven Small and his colleagues published their findings in the Dec. 20, 2007, issue of the journal Neuron, published by Cell Press.

New brain mechanism identified for interpreting speech
12-19-2007 · EurekAlert!
In conversation, humans recognize words primarily from the sounds they hear. However, scientists have long known that what humans perceive goes beyond the sounds and even the sights of speech. The brain constructs its own unique interpretation. In a study in the Dec. 20 issue of Neuron, researchers at the University of Chicago identify brain areas responsible for this perception. One of these areas, Broca's region, is typically thought of as an area of the brain used for talking rather than listening.

Bird song study gives clues to human stuttering
06-11-2007 · EurekAlert!
Researchers at the Methodist Neurological Institute in Houston and Weill Cornell Medical College in New York City used functional MRI to determine that songbirds have a pronounced right-brain response to the sound of songs, establishing a foundational study for future research on songbird models of speech disorders such as stuttering, as reported today in Proceedings of the National Academy of Sciences.

Sensory Feedback During Speech: The Brain Attunes To More Than Just Sound
10-11-2006 · ScienceDaily
Using robotics to manipulate the brain's perception of jaw movement while words are spoken, researchers have deepened our understanding of the importance of non-auditory sensory cues in the brain's control of speech. The findings are reported by Sazzad Nasir and David Ostry of McGill University and appear in the October 10th issue of the journal Current Biology, published by Cell Press.

Brain implant turn thoughts to words
11-14-2007 · EurekAlert!
Signals from an electrode implanted in the area of the brain responsible for generating speech, could help paralysed people get their "voice" back. Neuroscientists are able to record the signals from the neurons that surround the electrode. By analyzing the signals created when a "locked-in" patient imagines speaking, researchers have developed software that they hope one day will turn their thoughts into speech.

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too
10-18-2006 · EurekAlert!
For years, the brain chemical dopamine has been thought of as the brain's "pleasure chemical," and studies have linked the addictive properties of drugs like cocaine to their effects on the dopamine system. But now, a new study adds a new twist to dopamine's fun-loving reputation: pain.
