"The second breakthrough: this pair of eyes on the Artificial Brain can now recognize colors!"
Song He picked up the culture vessel and placed it inside the instrument, then took three sheets of colored paper—red, green, and blue—from his pocket.
He stuck the red paper against the vessel wall and turned on a flashlight, letting red light suffuse the culture medium.
The students crowded around the instrument's screen. One region of the brain quickly lit up!
Song He switched to the blue paper. After the flashlight filled the culture medium with blue light, the highlighted region of the brain immediately shifted to the other side!
He switched to the green paper, and the highlighted region changed again!
"As everyone knows, S Short-Wave Cone Cells, M Medium-Wave Cone Cells, and L Long-Wave Cone Cells can see blue, green, and red respectively!"
"Therefore, this Artificial Brain I cultivated can already distinguish colors with its two eyes. The world it sees is in color!"
"I also conducted a color-preference experiment. I used three flashlights to shine three different colors. This Artificial Brain clearly preferred red—it stared at the red light for 80% of the time, while the entire brain grew increasingly active."
After Song He finished his demonstration, the students wore solemn expressions.
A few weeks ago, the brains Song He had cultivated had yet to develop clear vision, and everyone had paid no attention.
But now, the situation had suddenly reversed. It had vision, and it even seemed extremely strong! Its eyeballs could follow moving objects and distinguish multiple colors!
"Good, that concludes all the demonstrations. Let's move on to the scoring!" Xiang Xiaotong walked over to the whiteboard and picked up a marker.
The four students gathered around, listening to the teacher nervously.
"As we discussed last week, this week's scores
