Biological knowledge returned something very interesting.
Cephalopods!
As the name implied, cephalopods looked as though they had nothing but a head and feet.
Those with eight feet were called octopuses, while those with eight feet plus two tentacles were called squid. Squid were further divided into cuttlefish and calamari.
For Brain Science to achieve meaningful results, cephalopod knowledge was also essential. It was like how students studying aircraft engines also had to learn a little about automobile engines—many fields of knowledge were interconnected.
Among the animals in nature, cephalopods ranked among the most intelligent. Captive squid could remember feeding times, octopuses could quickly navigate mazes and complete puzzles, and certain records even suggested that octopuses could distinguish human faces.
Song He did not know much about octopuses. He had probably only memorized five or six crates' worth of papers, so he could only claim to have a passing understanding.
Therefore, the unfamiliar cephalopod knowledge provided by the Knowledge Rebate inevitably made his eyes light up!
The first thing he saw was a diagram of the nervous system of some giant cephalopod. The nervous system had actually been divided into four layers, each represented by a different color. Every layer was independent while also being faintly connected to the others.
Judging from the scale on the diagram, this cephalopod had reached a terrifying length of eight meters. Since there was no image of its appearance, only a neural diagram, it was difficult to tell whether it was the legendary Giant Squid or some other unknown species.
Next came a large pile of tidbits about cephalopod nervous systems, especially a number of novel neural circuits.
With Song He's extensive knowledge of the nervous system, he had never even heard of these neural circuits. The operating patterns of some of them could only
