词汇 | hypothalamic |
释义 | hypothalamic adjective anatomy specializeduk /ˌhaɪ.pəʊ.θəˈlæm.ɪk/ us /ˌhaɪ.poʊ.θəˈlæm.ɪk/ relating to the hypothalamus(= a small part of the brain that controls things such as body temperature and the release of hormones): Hypothalamic activation can lead to pain-modifying effects by the release of substances such as endorphins. This can impact the development of hormonal stress responses, which are mediated by the hypothalamic - pituitary - adrenal axis. Hypothalamic hormones generally stimulate the anterior pituitary. This suggested that a hypothalamic imbalance may play an important role in initiating mental changes. Headache or visual field abnormalities are seen with pituitary or hypothalamic tumours.

In the above studies, neighbouring neurons synthesizing melaninconcentrating hormone, another lateral hypothalamic neuropeptide with multiple functions including stimulation of appetite, were shown to be intact. Separation induced changes in squirrel monkey hypothalamic - pituitary - adrenal physiology resemble aspects of hypercortisolism in humans. Disruptions in serotonin system ontogeny in both receptor distribution and density of serotonin projections may also alter hypothalamic response to neuroendocrine challenge tests. Stress and the developing limbic - hypothalamic - pituitary - adrenal axis. These results suggest that an altered neuroendocrine stress response (dysfunctioning hypothalamic-pituitary-adrenal axis) is associated with the clinical state of schizophrenia. Influence of neonatal rearing conditions on stress-induced adrenocorticotropin responses and norepinephrine release in the hypothalamic paraventricular nucleus. Our results add to the growing body of literature showing the influence of maternal characteristics and environmental factors on hypothalamic-pituitary-adrenal axis patterns in children. Sparse but widespread retinal projections were apparent in other hypothalamic nuclei situated nearby. During infancy animals do not demonstrate hypothalamic-pituitary-adrenal axis responses to stress. Characterization of a 41-residue ovine hypothalamic peptide that stimulates secretion of corticotropin and beta-endorphin. The initiation of maternal behavior thus involves specific neural circuitry; and with pregnancy, structural and molecular changes occur in specific limbic, hypothalamic, and midbrain regions.
