Previous studies suggest that at poorer signal-to-noise ratios (SNRs), auditory cortical event-related potentials are weakened, prolonged, and show a shift in the functional lateralization of cerebral processing from left to right hemisphere. Increased right hemisphere involvement during speech-in-noise (SIN) processing may reflect the recruitment of(More)
If the vertical angulation of maxillary molar roots could be reliably predicted, this might affect the choice of roots resection procedures. In an attempt to develop this prediction, angulation of palatal roots was compared to palatal vault height. Human cadaveric maxillae with molars were sectioned faciopalatally through each tooth root to the palatal(More)
Blindness has evolved repeatedly in cave-dwelling organisms, and many hypotheses have been proposed to explain this observation, including both accumulation of neutral loss-of-function mutations and adaptation to darkness. Investigating the loss of sight in cave dwellers presents an opportunity to understand the operation of fundamental evolutionary(More)
This teaching packet is designed to help teachers, primarily in the upper grades, talk with their students about art produced since 1950 and some of the issues it raises. The focus is on selected works from the collection of the National Gallery of Art. For more complete information about artists and movements of this period, see the resources listed in the(More)
1 Blindness has evolved repeatedly in cave-dwelling organisms, and investigating loss of sight presents an 2 opportunity to understand the operation of fundamental evolutionary processes, including drift, selection, 3 mutation, and migration. The observation of blind organisms has prompted many theories for their 4 blindness, including loss-by-disuse and(More)
