Human Brain Proven to Gain True Multi-Tasking Capacity Through Intensive Practice
A comprehensive study led by U.S. neuroscientists has revealed that the human brain can restructure its neural circuits through intensive practice to perform two mental processes simultaneously, completely and without interruption.
Neuroscientists from Georgetown University Medical Center in the U.S. have determined that the human brain restructures its neural circuits by putting specific tasks on autopilot through intensive practice, allowing it to perform two mental processes simultaneously without interruption.
Scope and Methodology of the Study
The study investigated whether the brain can actually perform simultaneous processing rather than rapidly switching between complex tasks. As part of the experiment, participants were subjected to more than 30,000 visual classification tests over the course of weeks.
Brain Scans and Architectural Change
At the beginning and end of the process, the brain activity of the subjects was scanned with millisecond precision using functional magnetic resonance imaging and electroencephalography methods. The scan results documented that the brain undergoes a vital architectural change during the learning process.
Role and Shift of the Prefrontal Cortex
In the early stages of the task, it was observed that the prefrontal cortex region, which manages the brain's high-level executive functions but can handle only a single demanding process at a time, worked intensively. This situation changed after weeks of practice.
Overcoming the Cognitive Bottleneck and the Temporal Cortex
It was determined that the brain shifted this task away from the cognitive bottleneck in the prefrontal region to the temporal cortex, where memory encoding and object recognition are managed. It was found that a new category-processing area formed in the temporal lobe and the task became automated.
Success in the Simultaneous Second Task
In the final stage of the study, participants were given a second mental task simultaneously. It was determined that the subjects who succeeded in transferring the visual classification job to the temporal lobe freed up their prefrontal cortex and completed the second task flawlessly.
Expert Opinion and Results
Study author and neuroscientist Maximilian Riesenhuber stated that the findings prove the brain does not merely switch between tasks, contrary to what was previously believed. It was emphasized that the circuits are physically redirected and a true multi-tasking capacity is achieved.
