Music for concentration
Posted by: | CommentsA large number of studies have been made about the relation between the effect of music on the human brain in an article about the biology of music William J Crommie wrote :
Some brain circuits respond specifically to music; but, as you would expect, parts of these circuits participate in other forms of sound processing. For example, the region of the brain dedicated to perfect pitch is also involved in speech perception.
Music and other sounds entering the ears go to the auditory cortex, assemblages of cells just above both ears. The right side of the cortex is crucial for perceiving pitch as well as certain aspects of melody, harmony, timbre, and rhythm. (All the people tested were right-handed, so brain preferences may differ in lefties.)
The left side of the brain in most people excels at processing rapid changes in frequency and intensity, both in music and words. Such rapid changes occur when someone plucks a violin string versus running a bow across it.
Both left and right sides are necessary for complete perception of rhythm. For example, both hemispheres need to be working to tell the difference between three-quarter and four-quarter time.
The front part of your brain (frontal cortex), where working memories are stored, also plays a role in rhythm and melody perception.
Scientists concerned about BCI video games
Posted by: | CommentsI previously posted about Emotiv and Neurosky these companies develop video games that use BCI (Brain Computer Interface) basically you directly control your actions in the video game from your brain without using some kind of joystick .
Some problems sufarced with such technologies in some cases the game force the user to slow down his brainwaves this leave the user lacking concentration and feeling fatigue, if a game user takes a car after such a game or operate a dangerous machine then he might face some severe trouble.
Some scientists are concerned about that. BCIs are great for gamers with disabilities, but may not be so good for the general public, says Michelle Hinn, chair of the International Game Developers Association’s Game Accessibility Special Interest Group. Hinn adds “I can’t say that this (BCI-based games) won’t cause attention deficits, because that’s a very real possibility and a very real concern,”
For some strange reasons BCI games companies Emotiv and Neurosky claim that their games aren’t neurofeedback , however, their game do affect brain-waves pattern therefore it is neurofeedback (A method to train brainwaves pattern activity)
I’m curious where all of that will lead us you can read more about this story in a Wired article.

Open-Focus Brain
Posted by: | CommentsOpen Focus Brain is a new book by clinician and researcher in biofeedback, Fehmi. Fehmi draws on his experience with neurofeedback (brain-wave biofeedback) to explain how we can shift our brain waves to attain open focus. Open focus ?
I just read a full review of the book at OpEdNews. Open focus is a method to improve attention. The Amazon page
“Dr. Les Fehmi, a clinical psychologist and researcher, many of us have become stuck in “narrow-focus attention”: a tense, constricted, survival mode of attention that holds us in a state of chronic stress—and which lies at the root of common ailments including anxiety, depression, ADD, stress-related migraines, and more. To improve these conditions, Dr. Fehmi explains that we must learn to return to a relaxed, diffuse, and creative form of attention, which he calls “Open Focus.”

Spelling and Grammar?
Posted by: | CommentsSpelling and grammar are something I will have to be more careful with.
Lately, I received a lot of complaints about that.
I have well beyond 200 posts on this blog, I think I will correct them as I receive complaints.
I will also review the most read entries, so if you are a regular here in the future feel free to report me grammar and spelling disasters.
Thanks
About grammar and spelling Klaus J. Joehle wrote in the introduction of his book The Messenger: Living on Love
Spelling and Grammar?
Perfect spelling has never fed a hungry child.
Perfect grammar has never mended a broken heart
A finely pressed suit only hides the glow of love that is
missing
A lack of love is the only imperfection I know
So get over it
The need for Perfect spelling and perfect grammar
Is boring, time consuming elusions that hide what is truly
needed.
Thirty to fifty hours more editing would have made this perfect.
But instead it fed some starving children.
So I hope that each word and each sentence of imperfection
Reminds you of what’s really important.I did pay to have this book edited once and upon its return
there were still many errors.
After its return my wife took over and after many long hours of
editing and re-editing
She gave into one healthy fact of life
Nothing is Perfect
Or maybe it is
My wife believes everything is perfect in it’s own special way
