<s>[INST] I have always been fascinated by the idea of memory and how our brains process and store information. I've been reading about the concept of "flashbulb memories" which are incredibly vivid and detailed recollections of significant events. I'd love to learn more about them.

The concept of "flashbulb memories" was first coined by Brown and Kulik in the 1970s and refers to the vivid recollections of a person's memory for a significant event, such as the assassination of President John F. Kennedy or the Chernobyl nuclear disaster. These memories are often described as being unusually vivid and detailed. What are some key characteristics of flashbulb memories?[/INST]
