Scientists train brains to change in one hour

A new study conducted at D’Or Institute for Research and Education (IDOR) have concluded that less than one hour of brain training with neurofeedback leads to strengthening of neural connections and communication among brain areas.

Scientists train brains to change in one hour“We knew that the brain has an amazing ability to adapt itself, but we were not sure that we could observe these changes so quickly.

Understanding of how we can impact on brain wiring and functioning is the key to treat neurological disorders,” says Theo Marins, a biomedical scientist from IDOR and the Ph.D. responsible for the study.

Thirty-six healthy subjects participated in the study in which the goal was to increase the activity of brain regions involved in hand movements. However, instead of actually move their hand, participants were asked to only imagine the movement, in total rest.

Nineteen of them received the real brain training and the remaining seventeen were trained with placebo neurofeedback, for comparisons purposes.

Immediately before and after the brain training, which lasted around 30 minutes, their neural networks were scanned in order to investigate the impact of the neurofeedback on brain wiring and communication, also known as structural and functional connectivity.

The results show that the corpus callosum the major cerebral bridge that connects the right and left hemispheres exhibited increased integrity, and the neural network controlling the movements of the body became strengthened.

It seems that the whole system became more robust. Likewise, the training also had a positive impact on the default mode network, a brain network which is impaired after stroke, Parkinson’s and depression, for example.

“We showed that the neurofeedback can be considered a powerful tool to induce brain changes at record speed. Now, our goal is to develop new studies to test whether patients with neurological disorders can also benefit from it,” concludes Fernanda Tovar Moll, president of IDOR and leader of the study.
