Dr. Eddie Chang: The Science of Learning & Speaking Languages | Episode 95
Main Takeaways
The human brain is shaped by sounds heard during utero and early brain development.
During the critical period of brain development, patterns seen or heard become familiar, leading to the development of native language sensitivity.
Rats raised in white noise experienced delayed auditory cortex development, which may impact speech patterns.
Brain mapping can be used to stimulate or block areas of the brain to identify specific speech, language, or movement areas.
Epilepsy may not respond to medication and may require surgery or stimulators, but the ketogenic diet may help alleviate symptoms.
Language is heavily lateralized to one side of the brain, but recovery from stroke may result in a shift in the area of language control.
Stuttering affects the coordination of brain programming needed to produce fluid speech and may be provoked by anxiety.
Language consists of speech, semantics, and syntax, with speech being the production of audio communication.
Reading and writing map to the speech/sounds part of the brain, and dyslexia may result from a difficulty in phonological awareness.
Brain computer interfaces can translate digital signals from brain activity to speech, allowing individuals with certain types of paralysis to communicate verbally.
