By measuring blood flow in the brain, researchers have determined that both the left and right hemispheres are involved in decoding emotionally charged information.

The brain is divided into specialized regions. Neuroscientists are working to understand each region’s responsibilities.

To understand which regions are responsible for processing emotional information, researchers from Ghent University in Belgium used a technique called transcranial doppler ultrasonography to measure blood flow velocity in the brain.

Greater velocity implies more activity in a particular area because blood rushes in to provide active brain cells with oxygen and glucose.
