The Auditory Nervous System ILO 3 Ascending Auditory Pathway

Question 1

Name the three sections of the ascending auditory pathway

Answer 1

Brainstem, Midbrain, Forebrain

Question 2

What does CN stand for?

Answer 2

Cochlea Nucleus

Question 3

What does SOC stand for?

Answer 3

superior olivary complex

Question 4

What two places do signals pass through in the Brainstem?

Answer 4

Cochlea Nucleus and Superior Olivary Complex

Question 5

What process is happening in the brainstem?

Answer 5

Binaural Processing. This is the first stage of interaction of signals from both sides with parallel pathways.

Question 6

What process is happening in the Midbrain?

Answer 6

reintegration of the auditory image. It has auditory inputs and visual inputs linking sound to what we see or feel.

Question 7

What process is happening in the Forbrain?

Answer 7

Integration with other modalities, conciousness

Question 8

What two parts make up the midbrain

Answer 8

Lateral lemniscus and inferior colliculus

Question 9

What two parts make up the Forebrain

Answer 9

Medial geniculate body, auditory cortex

Question 10

If a sound signal enters the right ear, what hemisphere of the brain will the signal go?

Answer 10

Left Hemisphere (contralateral)

Question 11

The Ventral Cochlear Nucleus connects contralaterally to where?

Answer 11

The superior olivary complex

Question 12

The Dorsal Cochlear nucleus connects contralterally to where?

Answer 12

The Inferior Colliculus

Question 13

How do you measure the frequency passband of a neuron?

Answer 13

You measure its tuning curve
