What drives human reasoning? For years, neuroscientists had tried to pinpoint the region where human reasoning stems from using “meta-analysis” — the combination and interpretation of previous studies’ results — to no avail. However, a new method developed by scientists from Korea may be the key to finding out the answer. Accounting for the folded geometry of the brain’s surface, this new method has determined that the brain’s “multiple-demand system” – involved with the “selection of task-relevant stimuli” and “separation of successive…task steps” is the likely site of reason.
