"Activation of the dorsolateral PFC has been shown during resolution of interference of irrelevant task sets."
"Activation is mediated by the level of abstractness of the set switch in an anterior to posterior fashion within the PFC, with the most anterior activations elicited by set switches and the most posterior activations resulting from stimulus or perceptual switches."

"The mechanism of PFS is hypothesized to involve synchronization of several independent object-encoding neuronal ensembles (objectNEs). When objectNEs fire out-of-sync, the objects are perceived one at a time. However, once those objectNEs are time-shifted by the lateral prefrontal cortex (LPFC) to fire in-phase with each other, they are consciously experienced as one unified object or scene."

The striatum receives inputs from multiple cortical regions (Webster, 1961; Beckstead, 1979; Hintiryan et al., 2016; Hunnicutt et al., 2016), and prefrontal inputs to the striatum have been shown to play significant roles in both goal-directed, as well as habitual behavior (Gourley and Taylor, 2016; Smith and Laiks, 2017; Amaya and Smith, 2018). The major frontal structures that have been implicated in instrumental and automatic behaviors are the prelimbic cortex (PL) and infralimbic cortex (IL) Amaya and Smith, 2018 in the medial prefrontal cortex (mPFC), as well as the OFC located in the ventral part of the PFC.
Interestingly, the two substructures of the mPFC, the IL and PL, seem to play opposing roles in balancing between goal and habit, with the IL supporting habitual behavior, and the PL supporting goal-directed behavior (Smith and Laiks, 2017; Amaya and Smith, 2018).

The prelimbic (PL) cortex allows rodents to adapt their responding under changing experimental circumstances. In line with this, the PL cortex has been implicated in strategy set shifting, attentional set shifting, the resolution of response conflict, and the modulation of attention towards predictive stimuli.

However, the dmPFC has been strongly implicated in multiple aspects of behavioral flexibility including set-shifting (Ragozzino et al., 1999; Stefani et al., 2003; Floresco et al., 2006, 2008; Bissonette and Roesch, 2015; Powell and Redish, 2016; Brockett et al., 2020) and response inhibition (Bussey et al., 1996; Muir et al., 1996; Narayanan and Laubach, 2006; Jonkman et al., 2009; Terra et al., 2020; Hamel et al., 2022). Such studies have revealed that the dmPFC is important for withholding or otherwise modifying learned motor behaviors (e.g., instrumental habits), but do not directly address its role in negatively regulating Pavlovian incentive motivation as measured by PIT.

A brain chemical linked to pleasure and depression may also trigger fear, according to a new study. Researchers say this may explain why the neurotransmitter dopamine, known to cause addictive behavior, may also play a role in anxiety disorders.
"Showing that dopamine can enhance both approach and avoidance behaviors is an important finding," says Howard Fields, a neurobiologist at the University of California, San Francisco.

It is possible that these three dichotomies merge into one dichotomy.

"Neuroticism, according to Eysenck's theory, is based on activation thresholds in the sympathetic nervous system or visceral brain."
