Explore the intricate dynamics of the unconscious brain under general anesthesia in this 46-minute lecture by Emery Brown, Professor of Brain and Cognitive Sciences at MIT and Professor of Anesthesia at Harvard. Delve into how anesthetic drugs like Propofol alter neural oscillations in the brain, as measured by EEG. Examine a model of the neural circuitry underlying anesthesia's impact on neural signals and discover how these changes vary with age. Learn about potential clinical methods for actively restoring brain function post-anesthesia, which may lead to faster recovery and reduced cognitive dysfunction. Gain insights into the history of anesthesia, balanced general anesthesia, clinical electroencephalography of Propofol, and the differences between general anesthesia and sleep. Investigate the brain's response to anesthesia across different age groups and explore the concept of reanimation from general anesthesia. Understand the science behind anesthesia and its effects on the brain, including the mechanism of Ritalin in relation to anesthesia recovery.

Clearly explained video on anesthesia and brain .described about anesthesia is not the state of sleep. Videos are brief and simple .various waves of sleep and various changes in wave form in differen6 state of anesthesia given. It will have be better if some information about awareness in anesthesia is given .

Prof E Brown, lecture on The Dynamics of the Unconscious Brain Under General Anaesthesia is excellent for beginners. We have recently procured a pEEG monitor in our hospital and I use this routinely and it is fascinating to see the changes in electrophysiology as anaesthesia is induced and maintained and what's most spectacular is seeing the brain emerge from anaesthesia.
This is an excellent talk that I highly recommend. -
Fahd Alyamiجيده جدا استمتعت فيها واشكر كل القائمين على هذة الدورات التي تساعد الكثير من ممارسي مهنه التخدير على الاستفادة في مجال عملهم وتوسيع نطاق الفكر والمعرفة لديهم -
It was very informative and engaging. The newer drugs were added to the sides which were very thoughtful. Over all shot and helpful for a over view of the topic. In my clinical practice i haven't used this, but your video made it easy to understand. Will be looking forward to such topics.

Aizel Jane LimThe Dynamics of the Unconscious Brain Under General Anesthesia" offers a comprehensive understanding of how the brain behaves in an unconscious state induced by general anesthesia. This intriguing research sheds light on an area that has long been considered a mystery. The researchers meticulously examined the brain activity of participants under general anesthesia using advanced neuroimaging techniques. Their findings revealed surprising patterns of brain activity that deviated significantly from the norm during wakefulness or even in other states of altered consciousness. -
Mojolajesu OdugbesanConsidering I was just interested in seeing what would happen in the brain, I'm very impressed with the results. The teaching was interesting and well explained, I'll definitely recommend. -
It was such a great course about anesthesia, and I’m so proud by taking this as a student.
Thank you.
