Chang is involved in bioengineering to create devices that allow the brain to function at super physiological levels and help people with various syndromes overcome their deficits.
The discussion delves into how the brain encodes and decodes speech and language, emphasizing the relationship between neurosurgery and neuroscience research in understanding and treating speech and language disorders.
Chang's work on brain-machine interfaces for locked-in syndrome patients exemplifies the potential of neuroscience to significantly improve patients' quality of life and communication abilities.
The conversation touches on the potential for augmenting human brain capabilities through neurotechnology, raising ethical questions about augmentation and access to emerging technologies.
Chang shares personal insights into the importance of mental and physical well-being for neurosurgeons, highlighting how exercise and focused work in the operating room contribute to his performance and mental state.
Quotes
- `“`The brain is very sensitive to those kinds of changes. Sound change and speech change is completely normal and happens all the time.`“`
- `“`Stuttering is a condition where people have a predisposition to it, but it's not necessarily caused by anxiety. Anxiety can provoke it and make it worse.`“`
- `“`Memory is very distributed across the entire brain. It's not one particular area where that memory is stored.`“`
- `“`The pursuit of augmentation or performance enhancement is really not a new thing. It's part of what humans do in general.`“`
- `“`Being in the operating room, for me, is a sanctuary. I love being there because it detaches me from a lot of things that are preoccupying me.`“`
