Walking along the highway did nothing to diminish activity in the subgenual prefrontal cortex.
The precise mechanism by which ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, improves treatment-resistant depression has not been identified, though the prefrontal cortex is thought to play a role in modulating depression.
With this research, we are able to target the prefrontal cortex as a specific modulator of depressive-like behaviours; and obtain the optimum result for treatment with DBS.

These areas, the supplementary motor area, the pre-supplementary area and the right ventrolateral prefrontal cortex, are known to be linked to executive function.

However, proper function of the prefrontal cortex requires norepinephrine and dopamine level to also be within optimal level.
When a coping strategy seems not to be directly available (18) and fear-related emotions still persist after stimulus perception, increased activation in both the amygdala and the dorsomedial/dorsolateral prefrontal cortex constitutes a measure of the ongoing emotional conflict.
