Summary
The video discusses the development of treatments for stuttering, focusing on research conducted on stuttering in songbirds. It is found that damage to the basal ganglia, specifically the striatum, in songbirds leads to stuttering. The recovery of songbirds from stuttering is attributed to neurogenesis in their brains, which is not present in human or mammal brains. This discovery is connected to neurogenic stuttering in humans, where damage or disruption to the basal ganglia, particularly the speech part, can cause stuttering. The video mentions that adults with a stutter can repair their stutter through therapy, such as learning how to speak slower and tapping out a rhythm. Additionally, the video explores theories on why people might finish others' sentences, including the motor theory of speech perception and turn taking in conversation for social bonding.
