The figure below shows the rate-level functions of an auditory nerve fiber in response to four different pure tone frequencies. Determine the tuning curve for a spike rate of 15 spikes/sec Frequency (Hz) 250 500 1000 2000 Required Sound Level (dB SPL) [color1] [color2] [color3] [color4] Determine the response area at the sound level of 30 dB SPL Frequency (Hz) 250 500 1000 2000 Spike Rate (spikes/sec) [color5] [color6] [color7] [color8] What is the Characteristic Frequency of this auditory nerve fiber? [color9] Hz

What effect does the efferent feedback from the Medial Olivary Complex (MOC) have?

Tonotopicity is not maintained in primary auditory cortex.

Which of the following is NOT a feature of the tuning curve?

You win the lottery and are financially stable for the rest of your life; however, you must pick one productive thing to do during the days to fill your time. What do you pick? Think passion projects, odd jobs, easy jobs, etc.

In a linear system, the frequency composition of the input wave and the output wave are [a] (the same, different). In a nonlinear system, the frequency composition of the input wave and the output wave are [b] (the same, different). A [c] (linear, nonlinear) filter may produce additional sinusoids in the output that were not present in the input signal.  

Afferent nerve fibers primarily innervate with [color1] hair cells, and efferent nerve fibers primarily innervate with [color2] hair cells.
