Danielle was born with a birth defect which resulted in a lack of primary auditory cortex formation. Which of the following will likely result?
a. Danielle will not be about to hear from her right ear. b. Danielle will not be able to hear at all. c. Danielle will need to get tubes put in her ears and then wear a hearing aid in order to hear. d. Danielle will be able to hear a little from each ear. e. Danielle will not be able to hear from her left ear.

  • Biology -

    If the primary auditory cortex has not formed, she cannot hear at all. There would be no neurons to sense the impulses coming from her auditory nerves or any other source.

    A or E would result from damage to the auditory nerve from her ear or to the ear itself (e.g., tympanic membrane, ossicles).

    I hope this helps. Thanks for asking.
