Summary
We recently discovered that a primitive part of the visual pathway shows rhythmic nerve cell activity similar to slow brain waves recorded in sleep, anaesthesia, and epilepsy. We now plan to discover whether these primitive cells help to generate brain waves by measuring the timing of their activity together with brain waves in different visual and non-visual parts of the brain. This project will contribute to understanding the role of brain waves in normal brain function and epilepsy.
Organization Of Descending Auditory Projections From Inferior Colliculus To Cochlear Nucleus

Summary
Sensory information gains awareness by ascending brain pathways to reach consciousness. Descending projections, however, have grown in importance because of implications for feedback management of ascending signals. Studies of these pathways will provide insight into auditory processing with respect to selective volume control, calibration adjustments between the two ears, and the extraction of signals from background noise. The data could lead to new strategies for treating hearing disorders.
