Normal postnatal development of the scalp-recorded cochlear microphonic (CM) response and brainstem auditory evoked potential (BAEP) were studied in rat pups. BAEP latencies decreased and amplitudes increased as a function of maturation. These changes occurred rapidly between 14 and 23 days of age with gradual change occurring thereafter. The observed(More)
BACKGROUND Despite impressive results with the Lap-Band in Europe and Australia, the early Food and Drug Administration A trial in the United States showed fairly poor results. This prospective study attempts to determine if the Lap-Band can produce effective weight loss in morbidly obese Americans. METHODS Five hundred four consecutive patients have(More)
Rat BAEPs varied significantly as a function of gender and ethanol sedation as well as stimulus intensity and repetition rate. All BAEP wave latencies decreased and amplitudes increased with increasing stimulus intensity. Contrary to the prevailing view, the I-IV interpeak latency changed significantly as a function of stimulus intensity. In terms of(More)
Dose-effect analyses were used to monitor the development of tolerance for ethanol's effects on FR30 operant performance in rats under different conditions of chronic ethanol exposure: (a) pre-session ethanol injections (PRE) vs. post-session ethanol injections (POST) in Experiment 1; and (b) an ethanol liquid diet (ED) vs. a control diet (CD) in Experiment(More)
Physiological investigations have indicated that the ventrolateral surface of the medulla oblongata is involved in the chemical drive to respiration. In this investigation, light and electron microscopic investigations of the 3 chemosensitive regions reveal the following. (1) Evaginations of the ventral surface abut the overlying pia mater thereby(More)
Previous studies have shown that systemic administration of the opiate antagonist naloxone potentiates the ventilatory response to inspired carbon dioxide. The present study was designed to localize the site of action of naloxone for increasing the respiratory chemosensitivity to inhaled carbon dioxide (CO2) in cats. Naloxone applied topically to the caudal(More)
