Document Summary

The auditory cortex: a1 and a2 is just auditory cortex 1 and 2. A1 responds very well to pure tones has a tonotopic map. It has cells that are responsive to specific tones/ frequencies. As you work outwards and in particular towards the belt area you ll find cells that are looking for complex and meaningful tones. The where pathway travels up towards the parietal area, the. What pathway travels in a ventral direction towards the frontal lobe. We are not equally sensitive to all pitches. > auditory masking: occurs when one sound covers up another sound so it can t be heard very well. > effects of fatigue: if you hear a loud sound and test the person half a minute later, they lose their hearing perception at the frequency at which the loud sound was played. Complication #1: most of the sounds we hear are not pure tones, but a mixture of different frequencies.
