Magnetic resonance imaging offers a means of observing the internal structure of the brain where traditional procedures of embedding, sectioning, staining, mounting, and microscopic examination of thousands of sections are not practical. Furthermore, internal structures can be analyzed in their precise quantitative spatial interrelationships, which is(More)
This study examined changes in the acoustic and temporal structure of ultrasonic vocalizations as a function of age and correlated acoustic changes with vocal fold microstructure. Ultrasonic vocalizations were recorded in three age groups of male rats: aged (24-26 months), middle-aged (17-18 months), and young (4-5 months). Acoustic and structural changes(More)
A high water content lens (Scanlens 75, +14.5 dioptres) and a low water content lens (Bausch and Lomb Soflens H3, +14.5 dioptres) were compared with respect to corneal thickness response after 6 hours of wear in a provocative test on 12 aphakic eyes. The mean increase in central corneal thickness was 3.3% for Scanlens and 6.4% for Soflens. This difference(More)
