6. as children get older their system shifts from ----- dominated to ---.
11. Membrane potential is more negative than resting state due to slow closing of K+ channels.

4. when an infant has present OAEs but no reflexes, what test can you perform to confirm a problem?
7. true or false: with ototoxic treatments children are more susceptible to HL than adults.
8. when using OAE's to detect hearing loss be sure to include ---- and ----.
9. recording electrode on scalp or other places that is far from the neural generator.
10. a child has absent CEOAEs but present DPOAEs what degree of HL do they have?
11. low thresholds and small DR.
12. during depolarization what ions rush into the cell?
