A provocative article in an Issue of the Proceedings of the National Academy of Sciences by Columbia researchers (Saxe, Malleret, et al.) described a study in which scientists documented the consequences of blocking neurogenesis (the birthing of new neurons) on maze-learning in mice. Since we already know that the magnitude of neurogenesis in this brain…
While I was working in Mexico, my wife Diane spends much of each day in an immersion Spanish class. She began by taking Spanish classes at a local community center. Now that she has the basics, an immersion class in which you have to operate in the second language is pretty effective. After two weeks…
In an article in an issue of the New Yorker, Jerome Groopman writes lucidly about the explosion in the diagnosis of bipolar disorder in children. Reading it made me thank my lucky stars once again that I am not a child neurologist or child psychologist or child psychiatrist who actually has to address the problems…
Alvaro asked this question as a comment after a blog entry discussed recent evidence that physical exercise contributes to academic success. Alvaro, “smart”, like beauty, is in the eyes of the beholder. You do not necessarily want a computer jockey next to you in your foxhole. You do not necessarily want a great world scholar…
That was the headline in a Washington Post article written by Ronald Glasser, published on Sunday, April 8, 2007. It reported a rather astounding statistic that applies to veterans of the Iraq and Afghanistan Wars: About 30% of soldiers in those conflicts have been directly exposed to IED or other powerful explosions. That exposure has…
I was just training in BrainHQ this morning. Because I have been working on the development of these exercises over the past several years, I’ve spent many an hour hunched over my computer “trying to get the answer right” on model training programs!! My current goal is to make brain fitness training part of my regular…
I attended a scientific meeting a few years ago in which Bill Jenkins, the program development team leader at Scientific Learning, described a radically improved version of one of their middle- and high school-targeted language learning programs (which they call “Literacy Advanced”). They have completely re-worked the game-play aspects of these exercises. Changes resulted in…
Serum BDNF (brain-derived neurotrophin factor) has been repeatedly shown to be lower than normal in schizophrenic, bipolar and depressed patient populations. Moreover, the severity of manias or depression have been shown to be inversely correlated with serum BDNF. This key brain trophic factor plays a complicated panoply of roles in brain development, in maintaining the…
A study in an issue of the Archives of Pediatrics and Adolescent Medicine focussed on autism spectrum disorders. A paper in that issue authored by a public health economist, Dr. Michael Ganz, used a rich variety of sources to determine the societal costs of autism. In today’s dollars: $3.2 million/autistic individual/lifetime. $35 BILLION overall, in…
