Cryoprobe-induced apical lesions in the chinchilla. II. Effects on behavioral auditory thresholds.
Lesions of the hair cells in the cochlear apex were produced by a miniature cryoprobe and changes in behavioral auditory thresholds were measured. Monauralized adult chinchillas were behaviorally trained using operant procedures to produce pure-tone audiograms at frequencies from 63 Hz to 40 kHz. Following collection of baseline thresholds, the apical and middle turns of the experimental ear we...
متن کاملThe ovarian and uterine arteries in the chinchilla (Chinchilla lanigera).
The purpose of this study was to describe arteries supplying the ovaries and uterus in the chinchilla. Five healthy adult female chinchillas were used. In order to reveal the arterial network by dissecting under a stereoscopic microscope, latex coloured with red ink was injected through the common carotid artery. The ovaries of the chinchilla are supplied by the arteriae ovaricae which formed e...
متن کاملChronic Defibrillation Thresholds in Nonthoracotomy Implantable Defibrillator
Background To establish the chronic stability of defibrillation thresholds (DFTs) in a transvenous cardioverter/defibrillator (TCD) system, we studied 37 consecutive patients with TCD systems implanted for >6 months. Methods and Results DFT was measured by a step-down method at implant and 2 and 6 months later. The mean ejection fraction was 34.5±14.3%. Coronary artery disease with previous myo...
متن کاملFrequency discrimination in the chinchilla.
Chinchillas were trained with shock-avoidance procedures to discriminate or detect pure-tone frequency differences. Inital attempts at determining frequency-difference thresholds utilized a complex discrimination paradigm and a go-no-go response. Although discriminations of large frequency differences were obtained from chinchillas after considerable training, discriminations of small frequency...
متن کاملFrenkelia microti infection in a chinchilla (Chinchilla laniger) in the United States.
A Frenkelia microti tissue cyst was found in the brain of a chinchilla (Chinchilla laniger) used for biomedical research. This is the first report of Frenkelia infection in this animal in the United States.
