I just ordered the Biosensing Starter bundle.

And while I was browsing the OpenBCI website, I learned they sell another product called EmotiBit. This product measures physiological responses related to emotional states.

Which would be a great device to wear if I want to capture data that I can include to train an AI model.

This morning on my way to work I stumbled on Jack Dorsey's Twitter profile. And he recently shared a 3.5hr YouTube video by Andrej Karpathy where Andrej shares an in-depth review of how to train and develop LLMs and some mental models to understand "the psychology" of LLMs. Here's Andrej's tweet if you're interested in reading it.

Who is Anrej? I didn't know about him, but this is his current Twitter bio: "Building @EurekaLabsAI. Previously Director of AI @ Tesla, founding team @ OpenAI, CS231n/PhD @ Stanford. I like to train large deep neural nets 🤖🧠💥"

I wonder if it's possible to uncover the "signature brain activity" of emotions just by studying myself. I don't know if there's such a thing as signature brain activity for each emotion. I don't know how emotions are different from each other at a biological / neurological aspect.

But I am assuming that each emotion has a signature. And mapping / defining these signature brain activities for each emotion (and finding labels for different brain activities) could help us understand each other. And I wonder if I can train an LLM to output a list of emotions based on my brain activity data.

I also assume that the experiences or events that trigger certain brain activities (or emotions) change over time. But I wonder if the signature brain activity that is what we call "sadness" or "fear" or "anger" stays the same.

This would be wonderful! Because it would allow us to discover these emotional signatures for a wide spectrum of emotions and use it as a basis to see into ourselves and quantify what we are feeling.

I'm excited for when those signature emotional waves / brain activity patterns are discovered and accepted. Because the world will change. And our perception of ourselves will change, too.

I'm very curious about the relationships between all these different brain activity states / patterns. I'm very curious to see and measure how different feelings can be felt at the same time because all brain regions responsible for causing those emotions are "active." – like having multiple light bulbs turned on at home and each light bulb allows us to see the world from a different lens.

And maybe that's what emotions are – they are sensors and yet they are also lenses. I guess a lens (or an eye) is a sensor!

I wonder if emotions are like sensors. Like eyes. But each eye turns on (or opens) based on different triggers and experiences. And when these "emotional eyes" turn on we perceive the world differently which means we think and behave differently.

Which is why, maybe, there are so many different parts of me. Some that only "turn on" when I'm with my family. Other parts of me that "open up" when I'm with my girlfriend. And others that close and open when I'm at work with my co-workers.

These are all switches. Eyes. Lenses. Sensors. That influence our behavior.
