Transcranial Direct Current Stimulation can Boost Language Comprehension, Penn Study Finds

Stimulation of the brain’s left angular gyrus enhanced the comprehension of simple, two-word phrases

Still today, scientists have been unable to figure out how the human brain processes the words we hear and constructs complex concepts. According to a new study from the department of Neurology the Perelmena School of Medicine at the University of Pennsylvania, transcranial direct current stimulation (tDCS) can alter the ability to process language, allowing for faster comprehension of meaningful word combintations. “Integrating conceptual knowledge is one of the neural functions fundamental to human intelligence,” said the study’s first author Amy Price, a neuroscience graduate student at Penn. “For example, when we read or listen to a sentence, we need to combine, or integrate, the meaning of words to understand the full idea of the sentence. We perform this process effortlessly on a daily basis but it is quite a complex process and little is known about the brain regions that support this ability.” To read more on this study, click here
