Nya rön om stamning

En nyligen publicerad studie av forskare vid visar att blodflödet i Brocas area är reducerat hos personer som stammar. Ju kraftigare stamning, desto mer påtaglig minskning av blodflödet.

Huvudförfattaren Jay Desai:

“When other portions of the brain circuit related to speech were also affected according to our blood flow measurements, we saw more severe stuttering in both children and adults. Blood flow was inversely correlated to the degree of stuttering — the more severe the stuttering, the less blood flow to this part of the brain.”
