The chatbot's responses were found to be brief and lacking context, with only 2 out of 6 questions answered accurately.

Glutamate is the primary molecule that neurons use to communicate with each other.
Previously, scientists have mostly recorded when neurons fire output signals, but now with a new glutamate indicator, they can record the many inputs that causes cells to fire. 🧵
