Memory - Wikipedia, the free encyclopedia - 0 views

Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).

Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).

Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

Another news article discussing the views on year-round school. The article explains how the trend is continuing to grow and how there is often much misconception of the term "year-round." Year-round does not necessarily mean that the students will get fewer breaks than the traditional school hours. This article attempts to clear up some of the confusion involving the term "year-round" as related to grade school.

Our Courts - Homepage - 6 views
-
A free computer game for teenagers created with the help of former Supreme Court Justice Sandra Day O'Connor has made its online debut. "Supreme Decision," the first of several planned web-based games, went online in August as part of a project called Our Courts. In it, students can play a Supreme Court law clerk helping a justice with a tie-breaking vote over a First Amendment case. Backed by the Sandra Day O'Connor College of Law at Arizona State University and Georgetown University, the Our Courts project is designed to teach middle school students about the Constitution and the courts. O'Connor, the first woman to serve on the Supreme Court, has said more people can name an "American Idol" judge than the three branches of government. Besides teaching about civics, she hopes the Our Courts project will help students learn how to analyze problems and develop arguments. In "Supreme Decision," students play a law clerk and must help fictional Justice Irene Waters write the majority opinion on whether a school can ban students from wearing music band T-shirts. Another game, called "Do I Have a Right," will be released soon. In that game, students will play the director of a constitutional law firm who must decide which amendment resolves a problem posed by a client.

The Real Value of Chinese Yuan
-
The romanised symbol is ¥ while in Chinese it is also written with the character 元. As of August 2008, 100 Chinese Yuan (RMB or CNY) equals to 14.5811 USD, 9.71331 EUR, 15.5370 CAD, 16.3896 AUD, 7.59939 GBP or 1,602.14 JPY.
-
Many economists believe that Chinese Yuan has become undervalued in the international currency exchange market. Chinese exports is costing too little in international markets, and imports from abroad is costing the Japanese too much. Chinese Yuan is slowly appreciating against the US Dollar and other major currencies of the world during the past two years.
