Dopamine: Burning the Candle at Both Ends
نویسندگان
چکیده
Dopamine neurons are well known for signaling reward-prediction errors. In this issue, Matsumoto and Takada (2013) show that some dopamine neurons also signal salient events during progression through a visual search task requiring working memory and sustained attention.

The role of human activities on number concentration and size distribution of particles in indoor air
Particle number concentrations and size distributions have been monitored in the kitchen during candle burning and smoking a cigarette with a Scanning Mobility Particle Sizer. Burning a candle produces particles in size range of 6–15 nm, whereas during smoking a cigarette, larger particles are formed in size range of 40–150 nm. Total concentration of particles increased up to 1,341,000 and 423,...
متن کاملThe Impact of Candle Burning During All Saints’ Day Ceremonies on Ambient Alkyl-Substituted Benzene Concentrations
Research findings concerning benzene, toluene, ethylobenzene, meta-, para- and ortho-xylene as well as styrene (BTEXS) emission at public cemeteries during All Saints' Day are presented here. Tests were carried out at town-located cemeteries in Opole and Grodków (southern Poland) and, as a benchmark, at the centres of those same towns. The purpose of the study was to estimate BTEXS emissions ca...
متن کاملExposure of churchgoers to airborne particles.
Particle mass and number measurements in a church indicate significant increases of indoor particle concentrations during the burning of incense. Generally, varying concentration regimes can be attributed to different "modes of indoor activity" and emission sources. While periods of candle burning are negligible concerning particle concentrations, increases by a factor of 6.9 and 9.1 during inc...
متن کاملThe Effect of Oxidation of Filtrates of a Chicken Sarcoma (chicken Tumor I—rous)
1. The rapid autoinactivation at 37 degrees of candle filtrates of the Rous Foul Sarcoma I is due in large part to oxidation. 2. Such oxidation may be prevented by a dilution of 1-2000 cysteine hydrochloride brought to pH 7.4 with NaOH. 3. The variability of infectiousness of candle filtrates is due in part at least to oxidative changes which take place during their preparation; and more active...
متن کاملP02-009 - Candle syndrome: expanding spectrum
Introduction CANDLE syndrome is an exceptional inflammatory condition starting within the first months of life, and comprising elevated fever, panniculitis with lipoatrophy, purplish and swollen eyelids, arthralgia, and developmental retardation. Most patients carry homozygous mutations in the PSMB8 gene that impair the assembly of the immunoproteasome (iP) and lead to interferon g deregulation...
