The locus coeruleus (/ s ɪ ˈ r uː l i ə s /) (LC), also spelled locus caeruleus or locus ceruleus, [1] is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic. [2] It is a part of the reticular activating system in the reticular formation.
Of relevance to both health psychology and the psychology of religion is the work of Holt, Clark, Kreuter and Rubio (2003) on a questionnaire to assess spiritual-health locus of control. The authors distinguished between an active spiritual-health locus of control (in which "God empowers the individual to take healthy actions" [ 38 ] ) and a ...
An allele [1], or allelomorph, is a variant of the sequence of nucleotides at a particular location, or locus, on a DNA molecule. [2]Alleles can differ at a single position through single nucleotide polymorphisms (SNP), [3] but they can also have insertions and deletions of up to several thousand base pairs.
Locus (mathematics), the set of points satisfying a particular condition, often forming a curve; Root locus analysis, a diagram visualizing the position of roots as a parameter changes; Locus (archaeology), the smallest definable unit in stratigraphy; Locus (genetics), the position of a gene or other significant sequence on a chromosome
A quantitative trait locus (QTL) is a region of DNA which is associated with a particular phenotypic trait, which varies in degree and which can be attributed to polygenic effects, i.e., the product of two or more genes, and their environment. [2] These QTLs are often found on different chromosomes.
In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
Julian B. Rotter (October 22, 1916 – January 6, 2014) was an American psychologist known for developing social learning theory and research into locus of control.He was a faculty member at Ohio State University and then the University of Connecticut.
A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. [1] In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic. [2] Gene polymorphisms can occur in any region of the genome.
