Functional clustering of neurons in motor cortex determined by cellular resolution imaging in awake behaving mice.

2 Nov 2009 Macroscopic (millimeter scale) functional clustering is a hallmark characteristic of motor cortex spatial organization in awake behaving mammals; however, almost no information is known about the functional micro-organization (approximately 100 ... Read more...

Density of tobacco retailers near schools: effects on tobacco use among students.

30 Oct 2009 OBJECTIVES: We examined the relationship between students' tobacco use and the density and proximity of tobacco retailers near their schools. METHODS: We used data from the 2003-2004 California Student Tobacco Survey and California retail licensing ... Read more...

Common candidate gene variants are associated with QT interval duration in the general population.

23 Oct 2009 OBJECTIVES: QT interval prolongation is associated with increased risk of sudden cardiac death at the population level. As 30-40% of the QT-interval variability is heritable, we tested the association of common LQTS and NOS1AP gene variants with QT ... Read more...

Technical information about 'Cluster Analysis'

Definition: A set of statistical methods used to group variables or observations into strongly inter-related subgroups. In epidemiology, it may be used to analyze a closely grouped series of events or cases of disease or other health-related phenomenon with well-defined distribution patterns in relation to time or place or both.
