This page has been created to expose the PartiallyOverlaps relationship between brain regions. This is not a static list, rather using this relationship in any brain region will add that content to this page.

Dorsolateral prefrontal cortex UBERON:0009834 Part of prefrontal cortex. The dorsolateral prefrontal cortex (DL-PFC or DLPFC), according to a more restricted definition, is roughly equivalent to Brodmann areas 9 and 46. According to a broader definition DL-PFC consists of the lateral portions of Brodmann areas 9 – 12, of areas 45, 46, and the superior part of area 47. These regions mainly receive their blood supply from the middle cerebral artery. With respect to neurotransmitter systems, there is evidence that dopamine plays a particularly important role in DL-PFC.DL-PFC is connected to the orbitofrontal cortex, and to a variety of brain areas, which include the thalamus, parts of the basal ganglia (the dorsal caudate nucleus), the hippocampus, and primary and secondary association areas of neocortex, including posterior temporal, parietal, and occipital areas check dorsolateral prefrontal neocortex ( Brodmann (1909) area 9

Nucleus paramedianus dorsalis nlx_143549 Small nucleus in the brainstem of human, located adjacent and medial to the nucleus prepositus in the dorsal medulla, described in several atlases of human brain stem. In transverse sections, it is oval with its long axis aligned with the dorsal border of the brainstem. It begins at about the same A-P level as the nucleus prepositus, just rostral to the hypoglossal nucleus. It includes calretinin immunoreactive large cells with oval or polygonal cell bodies. Cells are not immunoreactive for either calbindin or parvalbumin, but a few fibers immunoreactive to each protein are found within its central region. Cells in PMD are also immunoreactive to nNOS, and immunoreactivity to a neurofilament protein shows many labeled cells and fibers. According to Baizer et al., no equivalent structure was observed in the cat, rat, mouse or monkey atlas although they did not look at the brains of the great apes.

Olfactory cortex birnlex_2707 Aggregate brain region defined as those areas of cerebral cortex receiving direct synaptic input from the olfactory bulb (Price, 1973). The most recognized structure is the piriform cortex (prepyriform area), but other areas are often included, e.g., the olfactory tubercle. Prepyriform area

Primary motor cortex nlx_143555 The part of the cerebral cortex that receives projections from the motor thalamus and which projects to motor neurons in the brainstem and spinal cord. The motor cortex corresponds to Brodmann's area 4 (MM). The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain. Of the three motor cortex areas, stimulation of the primary motor cortex requires the least amount of electrical current to elicit a movement. Brodmann 1909 area 4 human
