Question 31
A research team studying neural connectivity in the prefrontal cortex has mapped interactions between key neurons involved in decision-making processes. They modeled the network using a modified Watts-Strogatz approach with N=4 nodes (neurons) and the following adjacency matrix:
| P1 | P2 | P3 | P4 | |
|---|---|---|---|---|
| P1 | 0 | 1 | 0 | 1 |
| P2 | 1 | 0 | 1 | 0 |
| P3 | 0 | 1 | 0 | 1 |
| P4 | 1 | 0 | 1 | 0 |
Based on the above data, answer the given subquestions.
When a decision task is initiated, neuron 3 shows elevated firing rates, which researchers believe coordinates the decision-making process. After analyzing the network topology, the degree centrality of protein 3 is ______________
