Why some people can’t decide

Do you find it difficult to decide what to order for dinner every time you are in a restaurant? If yes, it could be due to interruption in the flow of communication between two areas of the brain which represent our preferences, says a new study.

The researchers used a non-invasive brain stimulation method that enables generation of coordinated oscillations in the activity of particular brain regions.

Using this technique, the researchers intensified or reduced the information flow between the prefrontal cortex located directly below the forehead and the parietal cortex just above both ears.

The participants had to make preference-based or purely sensory decisions about food. The researchers found that when information flow between the two brain regions was disrupted, the participants found it more difficult to state their preferences.

The findings were detailed in the journal Nature Communications.– IANS
