neuroendocrinology

n. the study of the relationships between the nervous system—especially the brain—and the endocrine system. Some cells within the nervous system release hormones into the local or systemic circulation; these are called neuroendocrine (or neurosecretory) cells. The hypothalamus, for example, produces releasing hormones that regulate secretion of pituitary hormones. Certain substances, such as norepinephrine, act both as hormones and as neurotransmitters. See also psychoneuroendocrinology. —neuroendocrinological adj. —neuroendocrinologist n.

within-subjects design

an experimental design in which the effects of treatments are seen through the comparison of scores of the same participant observed under all the treatment conditions. For example, teachers may want to give a pre- and postcourse survey of skills and attitudes to gauge how much both changed as a result of the course. Such a design could be analyzed with a dependent-samples t test, a within-subjects analysis of variance, or an analysis of covariance. Also called related-measures design; repeated measures design; within-groups design. Compare between-subjects design.
