Brain Processes Signals Practice Test

Model: A bright red stop sign (stimulus) is detected by eye receptors (detection). A signal travels to the brain. The brain receives the signal and processes it to interpret what is seen.

Which explanation describes how the brain processes signals, using evidence from the model?

Model: A bright flashlight (stimulus) shines into an eye receptor (detection). A signal travels along a pathway toward the brain. A simplified brain icon receives the signal and processes it to make sense of the light. Which explanation describes how the brain processes signals, based on the model and the idea that detection is different from processing?
