What is the function of the medial prefrontal cortex?

Recent advances suggest the medial prefrontal cortex plays an important regulatory role in numerous cognitive functions, including attention, inhibitory control, habit formation and working, spatial or long-term memory.

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 happens when the medial prefrontal cortex is damaged?

A person with damage to the prefrontal cortex might have blunted emotional responses, for instance. They might even become more aggressive and irritable, and struggle to initiate activities. Finally, they might perform poorly on tasks that require long-term planning and impulse inhibition.

What is the role of the medial prefrontal cortex in fear extinction?

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.

What is the medial prefrontal?

Medial prefrontal cortex (MPFC) is among those brain regions having the highest baseline metabolic activity at rest and one that exhibits decreases from this baseline across a wide variety of goal-directed behaviors in functional imaging studies.

Where is the medial prefrontal cortex?

the frontal cortex
1 Medial Prefrontal Cortex. The mPFC extends throughout the medial section of the frontal cortex and into the OFC (BA 10).

Where is the basolateral amygdala?

NUCLEI OF THE BASOLATERAL AMYGDALA 1A) is located dorsolateral to the medial nucleus. The BNC is located deep into the cortical and central nuclei. It consists of three main nuclei, the lateral (LA), basolateral (BL), and basomedial nuclei (BM), arranged from dorsal to ventral, respectively.

What is insular cortex?

The insular cortex is a cytoarchitectonically complex and richly connected structure that functions as a cortical hub involved in interoception, multimodal sensory processing, autonomic control, perceptual self-awareness, and emotional guidance of social behavior.

What is medial prefrontal cortex mPFC?

How do you activate the medial prefrontal cortex?

How to Strengthen Your Prefrontal Cortex

  1. Games: Word games, memory games, and puzzles are effective ways to strengthen your prefrontal cortex.
  2. Learning: Learning something new, like a language, instrument, or other skill, is even more effective than word games at enhancing your prefrontal cortex.

Which brain area is linked with fear conditioning?

Fear conditioning is thought to depend upon an area of the brain called the amygdala. The amygdala is involved in acquisition, storage, and expression of conditioned fear memory.

What part of the brain is fear learning?

the amygdala
The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.
