A new study by a University of Alberta researcher shows that children who stutter have less grey matter in key regions of the brain responsible for speech production than children who do not stutter.

A team of researchers at UC San Francisco has uncovered the neurological basis of speech motor control, the complex coordinated activity of tiny brain regions that controls our lips, jaw, tongue and larynx as we speak. Described this week in the journal Nature, the work has potential implications for developing computer-brain interfaces for artificial speech communication and for the treatment of speech disorders. It also sheds light on an ability that is unique to humans among living creatures but poorly understood.

Does the emotion in our voice have a lasting effect? According to Annett Schirmer and colleagues from the National University of Singapore, emotion helps us recognize words quicker and more accurately straight away. In the longer term however, we do not remember emotionally intoned speech as accurately as neutral speech. When we do remember the words, they have acquired an emotional value; for example words spoken in a sad voice are remembered as more negative than words spoken in a neutral voice.

A century and a half ago, French physician Pierre Paul Broca found that patients with damage to part of the brain’s frontal lobe were unable to speak more than a few words. Later dubbed Broca’s area, this region is believed to be critical for speech production and some aspects of language comprehension.

Unlike human speech, most of the squeaks, calls, and songs produced in the animal kingdom do not have to be learned -- the vast majority of animals rely on innate vocalizations for their acoustic communications. Only a few, such as songbirds, whales, and dolphins, are known to be vocal learners, modifying the sequence or pitch of their sounds based on what they hear from other members of their species. New evidence suggests another animal can be added to that list: mice.

Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism.
