The Brain’s Response to Auditory Stimuli

Good For:
Check out this video for a real-time visualization of the brain’s response to auditory stimuli. An inflated surface is used to expose information otherwise hidden by the naturally curved brain surface.

The data was obtained with a Magnetoencephalography (MEG) system located at Mass General’s Martinos Center for Biomedical Imaging. MEG can non-invasively provide data with a millisecond-temporal resolution. This makes it an ideal candidate for real-time monitoring and processing of neuronal activity. The MNE-CPP framework, developed by the Martinos Center and partners, offers software tools to acquire, process and visualize MEG data in real time.

About the

Cambridge Science Festival, the first of its kind in the United States, is a madcap celebration of science, technology, engineering, art, and math (STEAM). A multifaceted, multicultural event, the Festival makes science accessible, interactive, and fun, highlighting the impact of STEAM in all our lives.

For the 2021 Festival, we will host a month-long celebration of STEAM in our community with an overarching theme of gratitude and appreciation. During the month of April 2021, we will showcase creative digital and virtual entries from our rich STEAM community.
