The simplified mechanisms of drug action presented here are just a small part of the story. When drugs enter the body they elicit very complex effects in many different regions of the brain. Often they interact with many different types of neurotransmitters and may bind with a variety of receptor types in a variety of different locations. For example, THC in marijuana can bind with cannabinoid receptors located on the presynaptic and/or postsynaptic cell in a synapse.  Where applicable, this presentation primarily depicts how drugs interact with dopamine neurotransmitters because this website focuses on the brain's reward pathway. Mouse Party is designed to provide a small glimpse into the chemical interactions at the synaptic level that cause the drug user to feel 'high'.

"Laments about our schools are nothing new; everyone is an expert, it seems, when it comes to education. While most critics point to the lack of funding or the shortage of teachers, John Taylor Gatto insists the problem goes deeper; we've turned our schools, he says, into "torture chambers." If that sounds abrasively radical, consider this: Gatto, with almost thirty years' experience as a public-school teacher, has just been named New York City's Teacher of the Year for 1989. Gatto teaches seventh grade at Junior High School 54 on Manhattan's Upper West Side. Something of a local legend, he's a chess player and a songwriter - and he grows garlic. He was once named Citizen of the Week for coming to the aid of a woman who had been robbed. He has lectured on James Joyce's Ulysses at Cornell University and has taught philosophy at California State College. Perhaps it's not surprising that he's been approached by a film company interested in making a movie of his life. Gatto once ran for the New York State Senate on the Conservative Party ticket, and some of his ideas are quite traditional: he stresses "family values" and questions increased funds for education. But he's too much of a maverick to be easily labeled. At a recent hearing in New York, he castigated the school system for "the murder of 1 million black and Latino children," and was met with a standing ovation. What follows is the text of the speech he gave upon being named Teacher of the Year."

As Twitter surges toward an estimated 12 million registered users by year's end (though some new stats may disagree), some of us are starting to deal with what we recently dubbed "followholism." You've followed so many people, it's hard to keep up, and it's probably time to do a little housekeeping. But where do you begin? Twitter's own tools for managing followers are subpar. It's nearly impossible to figure out who among your followers are following you back, and the interface for paging through followers is clumsy and difficult to use. Fortunately, Twitter's API has given rise to a vast universe of amazing third party apps. So we've assembled a toolkit below of 10 services that can help you take control of Twitter and organize your followers. If you know any other tools that would be helpful for organizing tweeps, add them in the comments.
