Researchers use neural prosthetic device for recall of specific memories

Researchers at Wake Forest say they successfully implemented a prosthetic system that uses a person’s own memory patterns. This system facilitates the brain’s ability to encode and recall memory.

A team at Wake Forest and USC, led by Robert Hampson, first reported a study of this type of technology in 2018. In that previous study, the team based its electronic prosthetic system on a multi-input, multi-output (MIMO) nonlinear mathematic model. Researchers influenced the firing patterns of multiple neurons in the hippocampus, a part of the brain involved in making new memories.

Researchers now built a new model of processes that assists the hippocampus, helping people remember specific information. The team used recordings of neural activity in brain cells to create a memory decoding model (MDM). It let them decode what neural activity is used to store di…
