Mapping clinical tests of language and working memory at SNL 2018
Terri Scott, CNRLab member and PhD candidate in Neuroscience, presented her new research on the brain bases of nonword repetition – an important clinical assessment of language skills – at the recent meeting of the Society for the Neurobiology of Language in Quebec City. Terri discovered that the parts of the brain responsible for nonword repetition are also recruited for both language processing and working memory.

Dyslexia Paradox
Differences in how the brain adapts to sights and sounds could be at the root of reading disorders. Read the full story from Inside Sargent.
Dyslexia and the brain: A problem with rapid neural adaptation
Our new findings, published today in Neuron, reveal that the brains of children and adults with dyslexia show less rapid neural adaptation than the brains of typical readers. Rapid neural adaptation is a kind of learning that the brain does in just a few seconds to make perception more efficient. A dysfunction of rapid neural adaptation may make it difficult for individuals with dyslexia to coordinate the demanding neural plasticity involved in learning to read.

CNRLab projects featured on WBUR: “11 Young Neuroscientists Share Their Cutting-Edge Research”
Our ongoing research on the brain bases of language processing and language impairment was recently focused on Boston’s NPR station: WBUR 90.9. In this video, Dr. Perrachione describes the lab’s research using cutting-edge neuroimaging technologies like fMRI to help unravel the brain bases of language and memory.

Dyslexia also affects the ability to recognize voices
Although dyslexia is well known as a disorder that affects the development of typical reading ability, research from Dr. Tyler Perrachione (Principal Investigator of the Communication Neuroscience Research Laboratory at BU) and colleagues has revealed that individuals with dyslexia also have trouble learning to recognize voices compared to their peers with typical reading ability.
