PROFESSOR: OK, I guess
we'll get started.
Last time, we were talking
about the auditory pathway
in the brain, the
central auditory pathway,
starting with the
cochlear nucleus
and going up through
the various brain
stem, the thalamic and
cortical auditory areas.
And then we focused mainly
on the cochlear nucleus,
which is the very first of those
many auditory central nuclei.
And we talked
about the diversity
of cell types or neuron
types in the cochlear nucleus
and the diversity
of response types
when you monitor the responses
of single neurons to sound.
And we did some attempts at
correlation between the two.
And those are firmly established
in the cochlear nucleus,
much better than anywhere
else in the auditory
pathways certainly.
So any questions from last time?
So today's lecture is on
hearing loss and implants that
restore our sense of hearing
if we happen to be deaf.
And I've written
a little summary
of what I want to cover
today on the board.
So we'll start out with the
first 2/3 of the lecture being
on hearing loss.
And we've mentioned a little
about the conductive apparatus,
the eardrum, the three
