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.
The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate. Hindbrain (rhombencephalon)
This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an animal is bipedal or quadrupedal.
The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
Sagittal, a vertical plane that passes from between the nostrils, and between the cerebral hemispheres, dividing the brain into left and right halves. "Median plane" specifically defines the midline between left and right sides of the body. It contains the dorsoventral and medial axes of the brain.
The medial prefrontal cortex (mPFC) is composed of BA12, BA25, and anterior cingulate cortex: BA32, BA33, BA24. [1] Within that area is the dorsal nexus, which interconnects many parts of the brain. [19] The ventral prefrontal cortex is composed of areas BA11, BA13, and BA14. [1] (Also see the definition of the orbitofrontal cortex.)
The temporoparietal junction, located in the cortex is one of these brain regions. The temporoparietal junction is thought to integrate sensory information. The second portion of the brain thought to be involved in perception of embodiment is the extrastriate body area. The extrastriate body area is located in the lateral occipitotemporal cortex.
The prefix para meaning beside or adjacent to.) The paralimbic cortex, also referred to as the mesocortex , or juxtallocortex, is interposed between the neocortex and the allocortex . [ 3 ] The paralimbic cortex provides a gradual transition from primary limbic regions, including the septal region , substantia innominata , and the amygdala ...
