Suppose You Record from a Single Concept Cell to Which

question 9

Multiple Choice

Suppose you record from a single concept cell to which you show images of a famous person (or maybe a not-so-famous person, such as your sibling) . And then, suppose you display a series of images of the same person, but with each successive image, the face has been increasingly altered to the point that the face on the final image no longer bears any resemblance to the original face. In terms of action potential spike firing, how would the concept cell respond?

• A) The cell would continue to fire at the same intensity until the face images become too dissimilar and firing would abruptly stop; i.e., a threshold will be reached.
• B) The cell would continue to fire at the same intensity until the face images become too dissimilar and firing would abruptly decline, but not stop.
• C) The cell would continue to fire at the same intensity in response to all face images shown.
• D) The cell would significantly decrease firing intensity in response to the first significant alteration of the face.
• E) The cell would gradually decrease firing intensity as the resemblance to the original image decreases.
