  This Is Your Brain on Electricity 

  http://www.wired.com/medtech/health/news/2001/08/46278

  For decades, doctors have used pacemakers to regulate the heart. Now they're implanting similar devices into the brain. Thousands of patients with the most serious cases of Parkinson's disease and epilepsy ... have received the devices since they obtained approval in 1997 from the Food and Drug Administration . Hundreds more are slated to take part in clinical trials to see if the pacemakers' electrical impulses can control chronic pain, depression and even obesity. In America, over 1.2 million people suffering from depression have found that traditional medications don't work for them, say makers of the device. About 250,000 epileptics are in the same situation, as are nearly 100,000 sufferers of Parkinson's disease. So far, early results are positive. Dr. Rajesh Pahwa, an associate professor of neurology at , has implanted hundreds of the devices, finding that 80 percent of his pacemakered patients with Parkinson's showed significant improvement -- with a 40 percent reduction in need   [More...] [Less...]

  Electricity around the world: everything about plugs, sockets, voltages, converters, etc. 

  http://users.pandora.be/worldstandards/electricity.htm

  * In Brazil there is no standard voltage. Most states use 127 V electricity (Acre, Amapá, Amazonas, Espírito Santo, Mato Grosso do Sul, Maranhão, Pará, Paraná, Rondônia, Roraima, Sergipe and Minas Gerais). ... Other – mainly northeastern – states are on 220 V (Alagoas, Brasília, Ceará, Mato Grosso, Goiás, Paraíba, Rio Grande do Norte, Santa Catarina and Tocantins). Although in most parts of the states of Bahia, São Paulo, Rio de Janeiro and Rio Grande do Sul 127 V is used, the cities of Santos, Jequié, Jundiaí, São Bernardo do Campo, Novo Friburgo, Bagé, Caxias do Sul and Pelotas run on 220 V. The states of Pernambuco and Piauí use 220 V, except for the cities of Paulista and Teresina (127 V). ** Although the mains voltage in Japan is the same everywhere, the frequency differs from region to region. Eastern Japan uses predominantly 50 Hz (Tokyo, Kawasaki, Sapporo, Yokohoma, Sendai), whereas Western Japan prefers 60 Hz (Osaka, Kyoto, Nagoya, Hiroshima). *** Saudi Arabia uses 110 V in many p   [More...] [Less...]
