The dorsomedial prefrontal cortex (dmPFC) is part of the mentalizing network, a set of brain regions consistently engaged in inferring mental states.
Where is dmPFC?
Anatomical terms of neuroanatomy
The dorsomedial prefrontal cortex (dmPFC or DMPFC is a section of the prefrontal cortex in some species’ brain anatomy.
What does dorsolateral prefrontal cortex do?
The dorsolateral prefrontal cortex has been found to be involved in superordinate control functions for various cognitive tasks such as decision making, novelty detection, working memory, conflict management, mood regulation, theory of mind processing, and timing.
What does the Prelimbic cortex do?
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.
What is the prefrontal cortex?
The prefrontal cortex is a part of the brain located at the front of the frontal lobe . It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.
What does the dorsomedial do?
| Region Functions | Dorsal medial prefrontal cortex (dmPFC) Socially directed thoughts | Dorsolateral prefrontal cortex (dlPFC) Planning, problem solving, abstract thinking, verbal and design fluency, maintain and shift cognitive sets |

What is limbic system?
The limbic system is a collection of structures involved in processing emotion and memory , including the hippocampus, the amygdala, and the hypothalamus. ... These structures are known to be involved in the processing and regulating of emotions, the formation and storage of memories, sexual arousal, and learning.
What happens if the dorsolateral prefrontal cortex is damaged?
Lesions of the dorsolateral PFC (DLPFC), consisting of Brodmann areas (BA) 9 and 46 in the human (Fig. 2, left), can result in deficits across a wide range of functions, including working memory, rule-learning, planning, attention, and motivation (Fig. 3).
Is the DLPFC in the frontal lobe?
The DLPFC is not an anatomical structure, but rather a functional one. It lies in the middle frontal gyrus of humans (i.e., lateral part of Brodmann’s area (BA) 9 and 46).
What is the orbitofrontal cortex responsible for?
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making .
Do humans have Prelimbic cortex?
The dorsal anterior cingulate cortex (dACC) in humans and its rodent homolog, the prelimbic cortex (PL), are important for conditioned fear expression .
What is the Infralimbic cortex?
The infralimbic cortex (IL) is a cortical region in the ventromedial prefrontal cortex which is important in tonic inhibition of subcortical structures and emotional responses, such as fear.
What is the contribution of the medial prefrontal cortex to fear?
A triad of brain regions, including the prefrontal cortex, hippocampus, and amygdala, form an essential brain circuit involved in fear conditioning and extinction. Within this circuit, the prefrontal cortex is thought to exert top-down control over subcortical structures to regulate appropriate behavioral responses .
How can I make my prefrontal cortex stronger?
- Games: Word games, memory games, and puzzles are effective ways to strengthen your prefrontal cortex. ...
- Learning: Learning something new, like a language, instrument, or other skill, is even more effective than word games at enhancing your prefrontal cortex.
Can frontal lobe damage repair itself?
It’s possible for the brain to “rewire” itself to compensate for an injury to the frontal lobe and allow undamaged areas to take over a function! Therefore, even if you’ve suffered damage to the frontal lobe, this doesn’t automatically mean you have permanently lost an ability controlled by that area.
What can damage the prefrontal cortex?
A variety of conditions can damage the frontal lobe, including stroke, head trauma, and dementia .
