Steve Ramirez, an associate professor of psychological and brain sciences at Boston University, has explained how scientists can locate memories in the brains of rodents, trigger them artificially, and even remove them. His book, How to Change a Memory, was shortlisted for this year’s Royal Society Trivedi science book prize.
How Scientists Manipulate Memories
In a recent interview, Ramirez detailed the methods researchers use to identify specific memories within the brain. By studying rodents, scientists have been able to pinpoint the neural circuits associated with individual memories, allowing them to activate these circuits on demand.
The research goes beyond simple activation. Scientists have also demonstrated the ability to artificially trigger memories and, in some cases, eliminate them entirely. These experiments provide a deeper understanding of how memory works at a fundamental level.
Potential Applications for Humans
Ramirez also discussed what the practical applications of this science could one day mean for humans. While the work is currently focused on rodents, the implications for future therapies and treatments are significant. The ability to alter or remove memories could potentially help people suffering from trauma or other memory-related conditions.
