Scientists categorize neurons by the way the brain jiggles during a heartbeat

The brain jiggles when the heart beats, and now, researchers have found a way to use that motion to better study the differences between types of neurons. In a study appearing March 10 in the journal Cell Reports, researchers find that by analyzing the changes in the waveforms they record from neurons during a heartbeat, they can more accurately classify the different types of neurons in the human brain. This work, they say, could help us better understand how the different types of cells that exist in the brain interact together to produce cognition and behavior.
