It’s interesting thinking about the strings that connect us to other people. There are some people in my life who I’m connected to though others, yet those connections is stronger than some of my primary connections. What makes a connection strong? Is it simply frequency?
In neuro we learned about long-term potentiation (LTP). In LTP, frequent and persistent stimulation of neurons (especially in the brain) can strengthen the connection between them for the future. Conversely, infrequent stimulation leads to decreased connection strength. But having frequent contact with someone doesn’t mean your are going to be best friends with them, though it can certainly help facilitate it. There still needs to be something else. Is it personality? I feel like there are some many example of people who on paper, or based on personality or interests should get along, but it doesn’t always work out that way. To me it would make sense that people from 2 different friend groups that are connected through me should hit it off super well since they similarly get along with me, but that is not always the case. Certainly they may get a long, but sometimes it just doesn’t click.
