Project Details
Description
The tonotopic map of the avian basilar papilla (Callus domesticus)
will be identified for two age groups (E16-17 and 2 weeks post
hatch). This will be undertaken to test the hypothesis that the
tonotopic map changes substantially throughout development and is
not simply a "scale model" of the adult. To accomplish this, individual eighth nerve neurons will be
impaled. The characteristic frequency and spontaneous rate will
be determined. Horseradish-peroxidase (HRP) will be
iontophoretically injected into the cell and allowed to distribute
throughout the cell as a cell tag. Terminals in the basilar
papilla will then be identified histologically and their position
expressed as a percent of the total length and width of the basilar
papilla.
