VR technology could reveal how the brain forms memories – Troy Media

When you think of a vivid personal memory, you dont merely recall the bare facts of what happened you remember additional details like the emotions you felt, perhaps where you were standing when things unfolded, scents and sounds in the air.Peggy St. Jacques

Memories play such a key component in shaping who we are, saidPeggy St. Jacques, a psychology researcher in the University of AlbertasFaculty of Science.

Autobiographical memories, also known as real-world memories from ones past, are formed in a complex fashion, which is what makes them so challenging to study. In addition to knowing an event itself, these memories include components like visual perspective and spatial context. To be fully understood, they need to be examined in an immersive environment.

Memories are studied through functional neuroimaging such as fMRI scans, but this technology has offered limited insight into real-world memories because it doesnt allow a persons brain to be placed in that same immersive environment. St. Jacquess research is changing that.

Using extended reality technologies like 360-degree 3D video cameras and MRI-compatible binocular headsets allows individuals whose brains are being scanned to essentially be plunged into the real world, said St. Jacques, one of 118 exceptional early-career researchers across the U.S. and Canada who were namedSloan Research Fellows this week.

Although we know a lot about how the brain remembers real-world memories, understanding how the brain supports how we initially form real-world memories has been elusive, said St. Jacques, who also holds theCanada Research Chairin Cognitive Neuroscience of Memory and is a member of theNeuroscience and Mental Health Instituteat the U of A.

As she explained, participants in St. JacquessMemory for Events Labcan don virtual reality headsets while within an MRI scanner so that when the scan is being taken, theyre experiencing an immersive, 360-degree 3D video of the event.

While participants are doing that, theyre forming memories for those experiences, she said.

Once they exit the MRI scanner, participants can be questioned about what they recall from the experience, providing valuable insight into whats going on in the brain during the complex process of real-world memory formation.

We are understanding for the first time how the brain forms real-world memories. Weve never been able to do that before.

A thorough understanding of how these real-world memories are formed and how the brain supports them is critical in understanding disorders that affect our memories.

Tackling this big question of how the brain creates real-world memories has the potential to not only radically change how we understand memory, but it could lead to new insights in impairments and treatments of Alzheimers disease and PTSD.

The Sloan Research Fellowships are two-year, $75,000 awards given out each year by the Alfred P. Sloan Foundation to recognize distinguished performance by researchers considered to be the next generation of leaders in their fields. Fifty-one previous fellows have gone on to win a Nobel Prize.
