Memory is not a thing, it is a process.

When we think of memory, we often imagine a central place in the mind—a kind of repository where everything is stored. While memory does function somewhat like a filing system, with processes for storing and recalling information, it is not located in one specific place. Instead, memory is a series of processes occurring in different parts of the brain, all working together to create what we call memory.

Memories—whether they’re facts, events, or personal experiences—appear in our brains as electrical signals. These signals activate various regions of the brain. Rather than being stored in one place, memories are distributed across different areas.

A common myth to dispel is that memory is finite. Many of us think we have limited storage and need to be careful about how much we learn. In reality, the need to be selective isn’t because of storage limits, but because of time constraints. Life is short and precious, and we may not have enough time to commit everything we want to long-term memory.

The good news? There are virtually no limits to how much we can store, as long as we use effective methods for organizing memories. Techniques like mnemonic devices, focusing our attention when learning, and making meaningful connections with new information help in retaining it long-term. Regularly reviewing and recalling information over time ensures that it stays in our long-term memory.

I’ve learned a lot of these ideas from Higbee’s book Your Memory: How It Works and How to Improve It. If you’re curious about how memory works and want to improve your own, this is a great resource to start with.
