Scientists from Cornell University (USA) created miniature VR headsets called MouseGoggles to study memory and navigation processes in more depth. These devices are made from inexpensive components, such as smartwatch displays and tiny lenses. The headsets help to record neural activity with high accuracy. The study was published in Nature Methods.
In one experiment, scientists simulated the approach of a predator’s shadow. While the mice did not react on large VR screens, with headsets they showed a sharp fear, jumping in surprise. This proves that headsets create realistic virtual images. Also, the mice’s brains began to function better during the experiment. The researchers noted that the technology provides new opportunities to study complex brain processes such as memory and behavior, which can be reconstructed using the knowledge gained. This is especially valuable for research into neurodegenerative diseases such as Alzheimer’s disease.
