To investigate the interaction in speech perception of auditory information and lexical knowledge (in particular, knowledge of which phonetic sequences are words), acoustic continua varying in voice onset time were constructed so that for each acoustic continuum, one of the two possible phonetic categorizations made a word and the other did not. For(More)
To help resolve the controversy about the brain renin-angiotensin system, the distribution of immunoreactive angiotensin in the brains of male rats was analyzed using twelve different antibodies to angiotensin II, two of which had previously been reported to stain nerve fibers in the central nervous system. The distribution of angiotensin-converting enzyme(More)
Utilizing an immunocytochemical technique wherein two different antigens can be visualized on the same tissue section, angiotensin-like immunoreactivity was found in rat adenohypophyseal cells that showed staining with antisera to hLH, hFSH or human prolactin. Angiotensin-like immunoreactivity was not found in cells that showed staining with antisera to(More)
Rate of change in sodium and @otassium excretion after injection of aldostevone into the aorta and renal artery of the dog. Am. J. Physiol. Igs(2): 337-342. Ig#.-The rate of change in sodium and potassium excretion and reabsorption following the intra-arterial injection of single 2-, 5-or IO-pug doses of aldosterone was compared with the effect of similar(More)

1. The circumventricular organs (CVO) are structures that permit polypeptide hypothalamic hormones to leave the brain without disrupting the blood-brain barrier (BBB) and permit substances that do not cross the BBB to trigger changes in brain function. 2. In mammals, CVO include only the median eminence and adjacent neurohypophysis, organum vasculosum(More)

The role of brain catecholamines in the regulation of growth hormone secretion was investigated in pentobarbital-anesthetized dogs by using drugs which modify the function of adrenergic neurons and receptors. Intravenous administration of L-dopa produced a prompt, statistically significant increase in plasma growth hormone concentration. This response was(More)
The effects of ablation of the nucleus medianus on drinking and vasopressin secretion were studied in male Long-Evans rats. The amount of water drunk in 1 h was assessed after subcutaneous injection of 5.8% NaCl (13.34 mosm/kg) or of angiotensin II (1.5 mg/kg). In a separate test with no water available, plasma vasopressin was measured 15 min after the(More)
In addition to increasing blood pressure, stimulating aldosterone and vasopressin secretion, and increasing water intake, angiotensin II affects the secretion of anterior pituitary hormones. Some of these effects are direct. There are angiotensin II receptors on lactotropes and corticotropes in rats, and there may be receptors on thyrotropes and other(More)
