CN

Question 1

How many sections does the CN have? What are they?

Answer 1

-3: AVCN, PVCN, DCN

Question 2

How is the CN tonotopically organized?

Answer 2

• Low frequencies at lateral portion of each section
• High frequencies at medial portion of each section
• Each section of the CN is organized independently of the others

Question 3

What are the 5 main cell types in the CN?

Answer 3

• Spherical bushy cells
• Globular bushy cells
• Stellate cells
• Octopus cells
• Pyramidal cells

Question 4

What are the 5 main PSTH types in the CN?

Answer 4

• Primary like
• Primary with notch
• Chopper
• Onset
• Pauser

Question 5

Compared to the AN, the CN has this type of phase locking.

Answer 5

-Enhanced

Question 6

Where are the spherical and globular bushy cells? Where do they project? They effectively act as what?

Answer 6

• AVCN
• SOC via ventral acoustic stria
• Relay station

Question 7

Inhibition changes PSTHs. It also changes rate-level functions. What is one change that can occur for a rate-level function when there is inhibition as compared to when there is none.

Answer 7

-Creates a nonmonotonic rate-level function

Question 8

Which area has the best temporal processing in the CN? Spectral processing?

Answer 8

• Best temporal processing: AVCN

- Best spectral processing: DCN

Question 9

What is the largest outflow from the CN?

Answer 9

-Ventral acoustic stria (AVCN)
