The article discusses the results of the research team of American researchers from the University of Michigan: Soo-Eun Chang, David C. Zhu, Ai Leen Choo and Mike Anstatt (2013, 2015), which were published in the prestigious journal Brain. Studies were carried out in connection with the exploration of structural and functional differences in the brains of people who stutter, compared with people who speak fluently. The results provide evidence of multiple changes in the connections of the brain as the cause of stuttering. The discussion verified the existing theories of the origin of stuttering in comparison with the presented research and indicated the prospects of further investigations, concerning both theory and practice.
