What it is:IDroo is an educational multi user whiteboard that lets students instantly collaborate online. Everything that is drawn or written on the whiteboard is visible to all participants in real-time. IDroo supports an unlimited number of meeting participants, the only limitations are computer power and internet connection speed. There is a professional math typing tool built-in making it easy to teach or work through math problems collaboratively. Best of all, IDroo can be used with Skype! IDroo is free for non-commercial use. Now for the downfall (and this is a HUGE downfall in my humble opinion), IDroo is currently only available for Windows. I know, disappointment for us Mac lovers. *sigh* If you are using a Windows computer this is a great way to collaborate online!
“She came in, and the costume lady [Nancy McArdle] on ‘Annie Hall’ said, ‘Tell her not wear that. She can’t wear that. It’s so crazy.’ And I said, ‘Leave her. She’s a genius. Let’s just leave her alone and let her wear what she wants.’”

Music, an abstract stimulus, can arouse feelings of euphoria and craving, similar to tangible rewards that involve the striatal dopaminergic system. Using the neurochemical specificity of [11C]raclopride positron emission tomography scanning, combined with psychophysiological measures of autonomic nervous system activity, we found endogenous dopamine release in the striatum at peak emotional arousal during music listening. To examine the time course of dopamine release, we used functional magnetic resonance imaging with the same stimuli and listeners, and found a functional dissociation: the caudate was more involved during the anticipation and the nucleus accumbens was more involved during the experience of peak emotional responses to music. These results indicate that intense pleasure in response to music can lead to dopamine release in the striatal system. Notably, the anticipation of an abstract reward can result in dopamine release in an anatomical pathway distinct from that associated with the peak pleasure itself. Our results help to explain why music is of such high value across all human societies.
