Your brain plays 'tricks' to sync sights and sounds


To make sense of complex environments, brain waves constantly adapt, compensating for drastically different sound and vision processing speeds, researchers report.
Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds. ....

Study shows how our brains sync hearing with vision

Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.
One of the brain s tricks is temporal recalibration: altering our sense of time to synchronize our joint perception of sound and vision. A new study finds that recalibration depends on brain signals constantly adapting to our environment to sample, order and associate competing sensory inputs together. ....

NORTHFIELD, Vt. Norwich University officials announced that three professors have each earned a $25,000 Pilot Award from the Vermont Biomedical Research Network (VBRN) in support of research at Norwich University for 2021-22.
The awards are:
Dr. Natalie Cartwright, an assistant professor of mathematics, won an award for her project, “Youth Firearm Violence: A Machine Learning Approach.”
Dr. Helene Sisti, an assistant professor of psychology, secured an award for her project, “The Neural Dynamics of Real and Imagined Movement Using a Bimanual Learning Task.” ....
