Scientists have proven that the brain can work in true multitasking mode
Wichtigste Punkte
- Georgetown University scientists confirmed that the brain physically restructures as a skill is learned.
- Volunteers classified car images in over 30,000 trials over a 5-10 week period.
- As a result of practice, brain activity shifted to the memory and recognition region without conscious thought.
- This is shown as proof that the brain has the capacity to multitask.
In Zahlen
Researchers at Georgetown University in the US discovered that the brain physically restructures itself while learning a new skill and automates repeated actions. The findings refute previous theories that true multitasking is impossible. It also sheds light on how the brain not only switches rapidly between tasks but also learns to do multiple things at the same time.
As part of the experiment, volunteers classified images of cars via a mobile app for 5 to 10 weeks, completing more than 30 thousand trials. Scientists examined the participants' brain activity before and after the training using fMRI and EEG methods. At the beginning of the processing phase, the task activated the prefrontal cortex, which governs conscious decisions.
After a few weeks of practice, brain activity shifted to the temporal cortex, which is associated with memory and recognizing complex objects. The study's lead author, Patrick Cox, stated that this situation overcame the "bottleneck" in the prefrontal regions, transmitting information directly to the response centers. Scientists believe this discovery could help study automatic behaviors such as tendencies and harmful habits.

Häufige Fragen
- Is multitasking actually possible?
- Yes, according to the research, because the brain restructures itself through repetitive practice, it has the capacity to perform more than one task simultaneously.
- How did brain activity change during the experiment?
- Initially, the prefrontal cortex, which manages conscious decisions, was active, but after a while, the function shifted to the temporal cortex, responsible for memory and object recognition.
- What can the findings of this research help with?
- The findings are expected to contribute to understanding how automated behaviors are connected to unconscious processes and to the study of harmful habits.
