Temporarily shutting down the brain's 'control center' actually makes people better at some types of learning.

The Takeaway
While we usually think of the prefrontal cortex as essential for intelligence, this study proves it can actually interfere with our ability to pick up on environmental patterns; inhibiting it allows the brain to switch to a more effective, exploratory learning style.
From the abstract
The brain must balance the automatic extraction of environmental regularities with top-down cognitive control, yet the causal neural mechanisms governing this interplay are debated. In particular, the hemispheric contributions of the dorsolateral prefrontal cortex (DLPFC) remain unresolved. Here, we applied inhibitory repetitive transcranial magnetic stimulation (rTMS) to the left, right, or bilateral DLPFC in 95 healthy adults during a probabilistic sequence learning task. We found that inhibit
