Herpes simplex virus type 1 (HSV-1) infection of the brain is known to cause neurodegeneration including a possible cause of Alzheimer's Disease. Using hiPSC-derived brain organoids, the authors investigate the mechanisms and cellular responses to HSV-1 infection. Using the Maestro multi-well multielectrode array system, the authors were able to confirm the altered electrophysiological result upon infection. A drastic decrease in the number of spontaneous spikes recorded from infected organoids compared to uninfected organoids. These results suggest that brain organoids are a potential model for studying the mechanism of neurodegeneration due to HSV-1 infection.
