Secrets of Sleep Science: From Dreams to Disorders

Rated 5 out of 5 by from Very effective! I fell asleep 5 min into watching the course. I now us this class as a sleep aid and listen to it at a low volume until I doze of, works like a charm every time.

Rated 4 out of 5 by from Secrets of Sleep Science I wish you would ask me in a few weeks, after I have taken several of the lectures because I have only listened to two of them so that far. But I can say I am finding them fascinating to this point. I am finding the professor easy to listen to and his explanations are good. I am looking forward to viewing/listening to more of them.

Rated 5 out of 5 by from Excellent course! This is a very interesting and informative course! It is comprehensive and packed with interesting information. I would caution that it is very technical, with a lot of references to brain structures and biological and chemical processes. It is dense with material, and I've gone back and replayed quite a few segments several times to be sure i was following. This is not a self-help or how-to book. It is a great survey of current understanding of why and how we sleep. As a mental health provider who treats a lot of clients with insomnia and apnea, I've been able to better understand the nature of my clients' sleep problems, and to integrate these insights into my approach to helping clients.

Rated 2 out of 5 by from 1st 20 chpts for MDs & scientists; last 4 useful This looks like a formal 4th year college course with [bookend chapts] added for those of us who are not medical doctors or chemistry scientists. Professor Heller was great and his delivery even greater. So how can I rate something like this? To illustrate my point: if I gave a Nobel prize winner - which took the gold medal on “WHY BRASS DOORKNOBS ARE BETTER THAN BRONZE DOORKNOBS” – most of you would say “so what?” (1-star). But if you were in the door business, you’d give me rave reviews (5-stars) for the same course. Obviously relevance is key. Perhaps TheGreatCourses needs a second category rating (1-5 stars) of “NEWS I CAN USE”.

Rated 5 out of 5 by from good overview and great detail I suffer from sleep apnea fortunately diagnosed by my very capable GP some years ago. I found the course very very informative. The lecturer has a rapid fire style setting forth the research and drawing his conclusion.It is up to the student to decide if Dr. Heller is being preachy or just enthusiastic in some areas. I sympathize with his zeal because had my OSA not been diagnosed I would likely not be here to write this review. A minor semi complaint Dr. Heller in his commanding view of the research sets forth in some detail the sometimes gruesome procedures on lab animals used to obtain the information needed by scientists in this area of science. I'm not a PETA member but I winced once or twice. In summary, this is a great course. The necessary travels into molecular biology is a little dense but well explained with some appreciated humor from Dr. Heller. His lectures are well documented and his conclusions sound. Well worth the cost and the time.

Rated 4 out of 5 by from Sleep is a mysterious subject. We have only viewed three of the lectures, but have found them to be informative. They seem authoritative. We have some Fitbit data on our sleep, so his comments are striking near to home. But these lectures on sleep could use some more graphics, especially when talking about Fourier transforms of brain waves. Some spectral density plots would have been nice. But the lecturer gets his info across effectively.

Rated 4 out of 5 by from Detailed science of sleep Prof Heller is a fine lecturer &steeped in his subject. The science lectures on research in progress are perhaps beyond the average listener, but the course overall is timely & comprehensive.
