Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Data's analysis of his severed head in the 24th century reveals triolic wave damage and temporal displacement signatures. This evidence directly causes the Enterprise crew to investigate the Devidian threat, leading to Beverly Crusher's autopsy findings in 19th-century San Francisco that confirm the neural harvesting pattern."

Why This Matters Across Episodes
The longer arc this connection carries
The discovery of Data's head provides the initial proof of alien temporal interference, which is the causal foundation for the entire mission. Beverly's confirmation that neural energy is being drained is the direct investigative payoff of that initial discovery, connecting the episodes through a cause-and-effect investigative chain.
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
