Brain Myths Exploded: Lessons from Neuroscience

Rated 5 out of 5 by from Clear, interesting, and effective. I had watched this professor's earlier course and knew this one would be good. She is careful to define terms or concepts and offers examples by way of illustration at every turn. The idea of examining misconceptions (myths) in popular understanding of neuroscience is a great format for the course. It was excellent!

Rated 2 out of 5 by from Straw man When discussing global warming, she sets up a straw man and then attacks that. While thousands of scientists disagree with her viewpoint, the silly straw man creation was quite obvious. Ironically, this was on a lecture of being objective.

Rated 4 out of 5 by from Excellent topic and discussion Each lesson covered a common misconception in clear and convincing discussion. Very informative and well presented and very clear to even those without neuroscience background.

Rated 5 out of 5 by from Excellent Presentation My requirement from a generic TGC lecture like this (other than a few specific ones) is to get some knowledge about the topic and not to become an "expert" in it. If your requirement is the same, then go ahead with the rest of the review. Presentation : The first thing I need in any course is, it should capture my attention and I should not be forced to watch/listen to it just so that I can complete it.. This lecture more than satisfied that. I've listened to plenty of audio courses (especially TGC courses). This is the only one where I'd think "oh the lesson is over already" when it ends. The flow is fantastic. I'll blindly buy any other course from the same professor just for this aspect. Content: I was amazed at so many myths that I used to believe. The explanations to tell me that they are myths and are not true satisfied me. I don't want to research further and gather counter points and judge if the professor is right or wrong. As I said, I'm a causal listener and don't want to be an expert.

Rated 4 out of 5 by from Interesting lesson titles and presentation. In lesson 22 she used a disparaging tone when referring to chimps as monkeys, bur cimps are apes, not monkeys. This makes me wonder how much else of what she said was inaccurate.

Rated 2 out of 5 by from Serious Flaws The information part of this course seems okay, though not remarkable, but the "myths" set-up adds nothing but red herrings. The professor is so captured by the materialist/evolutionish mindset that she seems totally unaware of the fact. For example, she describes researchers, 30 years after Einstein's death, handling his brain, which she refers to has his "mind." She also seems to pick and choose a great deal how to interpret correlations. When it comes to mental illness, she wants to deny that it is caused by chemical imbalances, despite the clear fact that fiddling with chemical balances can have affects. I'm not saying it is or isn't, but her denial seems inconsistent with the facts she reports. If she weren't captured by the idiotic "myths" approach, she could simply report the facts: we don't have a good theory of mental disease, but we're pretty darn sure it's a real thing and that it seems to have, in at least some circumstances, physical manifestations, i.e. abnormalities in brain chemistry. Furthermore, again for reasons we don't understand, some chemicals, like SSRIs, can "cause" changes that often look like improvement. Those two sentences are a more accurate description of what we know about the chemistry of mental illness than her entire "myths" based lecture. When it comes to "are men's and women's brains different?" she interprets the fact that they (obviously -- could anyone doubt it?) have many similarities as somehow meaning that they are not different. Obviously there's a tremendous overlap between the distribution of male brains and female brains in terms of structure and function. But there is also statistically irrefutable evidence that male behavior is different from female behavior on average. And given her materialist view, she has to at least consider that this is biological and not environmental. Surely she knows that men are more violent, in essentially every culture ever studied. But, perhaps because it's not politically correct, she denies the differences are in the brain.

Rated 1 out of 5 by from A monumental feat of illogic! It's no coincidence that the word "exploded" is in the title of this course, because its very first lecture featured a feat of illogic so massive that my brain actually exploded. If this thinking is typical of the course, than the course is worthless. I sent it back. Let me specify: Prof. Viskontas cautions listeners to avoid the temptation to look to evolutionary explanations to provide a "just so" story for how our minds are. Fair enough. She then gives an example. Why are toddler boys more interested in vehicles while toddler girls are more interested in dolls? She cautions against accepting the evolutionary "just so" story as an explanation. Again, fair enough. The reason she gives for accepting the "just so" is faulty. She claims these stories "feed the myth that evolution had some design in mind." Indeed it might feed that myth. But it doesn't make the argument wrong. Perhaps the argument is true and we should still be cautious about believing the myth for other reasons. That's illogic number one. Illogic number two is this: even if the argument for the evolutionary reason for these differences is faulty, that doesn't mean that these differences are not evolutionary in origin. Professor Gimbel's Logic course will teach you that making a bad argument for a proposition doesn't make that proposition false. Perhaps the proposition is true but for a different reason. Satisfied that she's destroyed the argument for evolution, she doesn't explore any further reasons why somebody would believe the evolutionary argument. The third illogic is the cherry on top of her illogic sundae. Prof. Viskontas concludes on the basis of the above reasons that the "just-so" story evolutionary explanation is wrong. She then argues (without providing any additional reasons) that our current social environment is a much more likely explanation for these differences between boys and girls. I can't help but notice that hand-waving about our "current social environment" is a form of "just-so" story. If "just so" stories about evolution ought to "make you cringe", how come an evolutionary "just-so story" about our current social environment is a more likely explanation? What sloppy thinking! I have no desire to be "taught" further by a professor who insults my intelligence this much. For the record, I have no educated opinion as to why toddler boys and toddler girls are different and I'm skeptical both of the social and the evolutionary argument.
