Engrams Where Your Brain Keeps Memories

The video explores the physical nature of memories, explaining how they are formed and stored in the brain. It introduces the concept of engrams, the unique patterns of neurons that represent memories. Through various studies on mice, researchers have identified and manipulated these engrams, demonstrating the potential to alter, delete, and even implant memories. While these findings are promising, they are still in early stages, with potential applications for treating conditions like Alzheimer's and PTSD.

Explain how optogenetics was used in the studies mentioned to manipulate memories.

In what ways do the studies suggest that neuroscientists are advancing in understanding memory?

What implications do the findings about memory manipulation have for conditions like Alzheimer's?
