In one study, researchers found significantly differing activity between healthy and schizophrenic patients in the left dorsal parietal cortex and left ventrolateral prefrontal cortex; as these regions are essential components of a frontal-parietal executive system, hypo-activity in these regions for schizophrenia patients during working memory ...
In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
fMRI lie detection is a field of lie detection using functional magnetic resonance imaging ... increased activation in the right anterior prefrontal cortex, BA 10 ...
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.

Two areas of the brain that are important in retrieving self-knowledge are the medial prefrontal cortex and the medial posterior parietal cortex. [3] The posterior cingulate cortex , the anterior cingulate cortex , and medial prefrontal cortex are thought to combine to provide humans with the ability to self-reflect.
Research upon primates suggests that area 10 has inputs and output connections with other higher-order association cortex areas particularly in the prefrontal cortex while having few with primary sensory or motor areas. Its connections through the extreme capsule link it to the auditory and multisensory areas of the superior temporal sulcus.
The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...
Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. [1] [2] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. [3]
