The Neuroscience of Seeking Behavior

Source: Slate.com

I found this recent article in Slate fascinating. It draws on the research legacy of James Olds, who did some of the seminal experiments with electro-stimulation of the brain. He referred to certain reward centers for basic drives such as hunger and sex. These became known collectively as the “pleasure centers” of the brain.

Fine so far, but could there be other things driving us besides the basics? Apparently so. The article goes on to develop the theory that “Seeking” is an elemental drive on par with drugs, sex and rock ‘n’ roll. This helps explain our attraction to modern tools such as “crackberrys,” Google and Twitter.

Stereo Bluetooth Comes to the iPhone

Apple has finally adopted the bluetooth standard for stereo (called A2DP) in both its laptops and the iPhone. (This was a long time coming!)

I’ve been using this Plantroncs 855 headset for about a month. I’m generally pleased with it. The sound quality is reasonably good for music and great for voice, audio books, podcasts, etc.

The only major flaw is occasional skipping. The music drops out for about a second and then returns. I mostly notice this when walking and/or moving my right arm (which is just above the phone on my hip). It is worse with vigorous exercise and in buildings with intense RF activity (other cell phones and WiFi).

Two problems limit utility with the iPhone: 1) Apple has only implemented part of the control standard called AVRCP (play/pause works, but not next/prev track); and 2) Voice control does not activate with a simple press of the talk button (as it should). By accident I discovered that you have to press and hold the button for about 3 seconds (why?) to get the phone’s attention.

So, life in this arena is improving… but at a slower pace than one would expect. These standards are not new.  I note that prev/next already works with my OSX laptop, so this feature may come with the next rev of the iPhone OS. Better voice control? — I can dream can’t I?

Update 2012: I’ve abandoned this headset because it is too fragile for everyday use. I now use a Jabra Clipper which is not perfect, but is much sturdier.

Rocky Mountain National Park 2009

While in Colorado we had the opportunity to visit Rocky Mountain National Park.

The first day I hiked around the Bear Lake area and took HDR photos of the taller peaks. I was lucky the sky stayed clear until noon (gallery photos 1-15).

On the second day we did a car tour along Trail Ridge Road. There were more clouds and even some rain. At one point we hiked up to an alpine desert above 12,000 ft. These “mushroom rocks” offered an unusual photographic subject.

Along the way we saw both elk and the wily marmot.
