In the classroom, it is not easy to determine how the eye and ear works. We can use an eye chart or tuning forks, but that only tells us so much. Using models connected to a computer interface can actually allow us to see the action potentials generated by the eye and the ear based on what colors there are “seeing” and sounds they are “hearing”.
A microphone listens to the audio
The audio is broken down into 8 different frequency bands
Depending of the power in the different bands, different nerve cells will fire an action potential.
Each cell’s action potential is different. The recorded spikes can be sorted to analyze which nerve cells were active.
Spikes in response to different music concerts: Mozart: Flute Concerto No. 2, Tchaikovsky – 1812 Overture end, and Fur Elise
SpikesHistogram to different music concerts: Mozart: Flute Concerto No. 2, Tchaikovsky – 1812 Overture end, and Fur Elise
Each photo receptor will generate an action potential that can be recorded.
Different photo receptor produce different spikes.
