Pixie Dust Technologies, Inc. Shares Findings Presented at Neuroscience 2023 Conference Study Confirms that Sound Stimulation Synchronizes Gamma Waves in the Human Brain
New York, New York and Tokyo, Japan, February 2, 2024 – Pixie Dust Technologies, Inc. (Nasdaq: PXDT) (the "Company"), a Japanese technology company focused on commercializing innovative products and materials utilizing proprietary wave control technology, today announced its findings on Brain Activation and Cognitive Improvement by Sound Stimulation that were shared at the Neuroscience 2023 Conference in November 2023.※1
Previous studies have concluded that gamma waves are reduced in patients with dementia.※2 In addition, it has been reported that synchronizing gamma waves in the brain by presenting 40 Hz sensory stimuli (sound and light) can be expected to suppress cognitive decline and brain volume shrinkage.※3,4
In the study presented at Neuroscience 2023, participants were exposed to amplitude modulations of the original sound source, and brain activity showed significantly stronger synchronization. This result, showing that gamma waves can be synchronized not only by pulse sounds but also by amplitude-modulated sounds, suggests the possibility of arbitrarily selecting the target sound for modulation for the purpose of EEG (brain wave) synchronization. These results are expected to be useful for clinical application in the prevention of dementia.
The annual Neuroscience Conference is organized by the US-based Society for Neuroscience and is one of the largest scientific presentations on neuroscience in the world. The research announced today was conducted as part of the Company’s joint research with Shionogi & Co.,※5 a Japanese pharmaceutical company, and the National Institute of Advanced Industrial Science and Technology, a national research institute.
In the course of joint research with Shionogi based on the common concept of cognitive function care that integrates into daily life, the Company is jointly developing gamma wave sound that may lead to cognitive function care. The two companies will continue to provide new solutions to solve the problems faced by individuals by building further evidence for brain activation and improvement of cognitive function through sound stimulation. Together, they are working to realize a society in which dementia prevention and improvement of cognitive function are attainable for all individuals.
