Terri Scott, CNRLab member and PhD candidate in Neuroscience, presented her new research on functional convergence and divergence of the neurocomputational architectures for language and working memory at the recent meeting of the Society for Neuroscience in San Diego Terri discovered that just because there is functional overlap between two tasks in a particular brain area, that does not necessarily mean that they are supported by the same computational architectures in the underlying neural response.
Terri received a Trainee Professional Development Award from the Society for Neuroscience for this work.

The Perrachione Lab has been awarded a grant from the National Science Foundation (NSF) to study whether formal musical training is associated with enhanced neural processing and perception of sounds, including speech in noisy backgrounds. Music forms an important part of our lives and is one of the few universals shared by all human cultures. This project will test the hypothesis that early musical exposure has benefits that extend beyond music to critical aspects of human communication, such as speech perception in noise.
The Perrachione Lab at BU is one center in an nationwide collaboration pursuing this project, led by Andrew Oxenham at the University of Minnesota, and including other centers at Purdue University, Carnegie Mellon University, and the University of Rochester.
Title: "NeuroDataRR. Collaborative Research: Testing the relationship between musical training and enhanced neural coding and perception in noise."
Project Number: 1840818

CNRLab scientists are using the new Siemens 3T Prisma scanner at the BU Cognitive Neuroimaging Center to study how the brain consistently recognizes speech in different contexts. Read more about our experiences with the new imaging center in this article from BU Today.
A new paper in PNAS, coauthored by Terri Scott, CNRLab doctoral student, and researchers at Harvard (Ev Fedorenko) and MIT (Nancy Kanwisher), explores how the brain extracts meaning as sentences unfold. This work "opens up new avenues for investigating the sequence of neural events that underlie construction of linguistic meaning."

Dr. Perrachione presented work from the CNRLab at the Future of Language Science symposium at Northwestern University. The symposium included alumni presentations in celebration of the Department of Linguistics' 50th anniversary.
In his presentation, Dr. Perrachione reported new work conducted at Boston University studying how noninvasive brain stimulation can facilitate foreign language learning, and two ongoing projects with collaborators from MIT investigating how the brain changes as a result of foreign language learning.
