The salience network is theorised to mediate switching between the default mode network and frontoparietal network (central executive network). [1] [2] [3]The frontoparietal network (FPN), generally also known as the central executive network (CEN) or, more specifically, the lateral frontoparietal network (L-FPN) (see Nomenclature), is a large-scale brain network primarily composed of the ...

There may be more if the columns can overlap, as suggested by Tsunoda et al. [17] Jeff Hawkins claims that there are only 150,000 columns in the human neocortex, based on research made by his company Numenta. [18] There are claims that minicolumns may have as many as 400 principal cells, [19] but it is not clear if that includes glia cells.
An example that identified 10 large-scale brain networks from resting state fMRI activity through independent component analysis [15]. Because brain networks can be identified at various different resolutions and with various different neurobiological properties, there is currently no universal atlas of brain networks that fits all circumstances.

A cortical minicolumn (also called cortical microcolumn [1]) is a vertical column through the cortical layers of the brain. Neurons within the microcolumn "receive common inputs, have common outputs, are interconnected, and may well constitute a fundamental computational unit of the cerebral cortex".
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Coherent activity of large-scale brain activity may form dynamic links between brain areas required for the integration of distributed information. [ 18 ] Microglia – the major immune cells of the brain – have been shown to play an important role in shaping network connectivity, and thus, influencing neuronal network oscillations both ex ...
Second, brain image data can be acquired using different neuroimaging modalities. Third, brain properties can be analyzed at different scales (e.g. in the whole brain, regions of interest, cortical or subcortical structures). Fourth, the data can be subjected to different kinds of processing and analysis steps.
