Do you find it difficult to decide what to order for dinner when you are in a restaurant? It could be due to disrupted information flow between two brain regions.

The research team used transcranial alternating current stimulation, a non-invasive brain stimulation method that enables generation of coordinated oscillations in the activity of particular brain regions. The study participants did not realize that they were being stimulated. Using this technique, the team intensified or reduced the information flow between the prefrontal cortex located directly below the forehead and the parietal cortex just above both ears.
The study participants had to make preference-based or purely sensory decisions about food. The investigators found that when information flow between the two brain regions was disrupted, the participants found it more difficult to state their preferences. They did not find evidence of any gender-specific effects in the experiments.
The findings were published in Nature Communications.
