"This research shows for the first time that despite obvious physical differences in how signed and spoken languages are produced and comprehended, the neural timing and localization of the planning of phrases is comparable between American Sign Language and English," explains lead author Esti Blanco-Elorrieta, a doctoral student in New York University's Department of Psychology and NYU Abu Dhabi Institute.
The research is reported in the latest issue of the journal Scientific Reports.

"Although there are many reasons to believe that signed and spoken languages should be neurobiologically quite similar, evidence of overlapping computations at this level of detail is still a striking demonstration of the fundamental core of human language," adds senior author Liina Pylkkanen, a professor in New York University's Department of Linguistics and Department of Psychology.
The study also included Itamar Kastner, an NYU doctoral student at the time of the study and now at Berlin's Humboldt University, and Karen Emmorey, a professor at San Diego State University and a leading expert on sign language, who adds, "We can only discover what is universal to all human languages by studying sign languages."

Past research has shown that structurally, signed and spoken languages are fundamentally similar. However, less clear is whether the same circuitry in the brain underlies the construction of...
