Which of the following outcomes strongly supports the notion that a place code is involved in detecting medium to high-pitched sounds?
a. Antibiotics can kill hair cells in a basal to apical direction and produce
corresponding deficits in pitch perception.
b. Damage to the posterior temporal cortex impairs hearing.
c. Mutant mice that lack inner hair cells are unable to hear.
d. Overgrowth of bone over the round window impairs hearing of high-, but not low-, pitched sounds.
e. Antibiotics can degenerate hair cells in an apical to basal direction and produce
corresponding deficits in intensity perception.
