Image of the Month: Neural tracts involved in speech recovery after stroke

Speech is our primary way of communicating with others. We speak without effort and relatively fast. “When we talk, we say on average two to three words per second, out of an active vocabulary of tens of thousands of words. There is an infinite number of word combinations, yet we say words in the proper order with the right sounds,” says Dr. Tatiana Schnur. “Language is essential to human interaction, yet little is known about how it happens in both the brain and the mind.”

Neural tracks involved in speech recovery after stroke. They include the frontal aslant tract (red) and the long (green) and posterior segments (blue) of the arcuate fasciculus. Image courtesy of Dr. T. Schnur.

In her lab, Schnur and her colleagues use a combination of behavioral, neuropsychological and neuroscience methods to answer questions about the paths to normal speech in the brain.  Furthermore, her lab investigates what drives successful recovery of language production following stroke.
