The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found primarily in the Neotropical realm. Genera
Cell group B9 is a group of cells located in the pontine tegmentum, ventral to serotonergic group B8. In the nonhuman primate they are found in the ventral part of the superior central nucleus and adjacent structures. [3] In the rodent they have a more lateral location within the medial lemniscus of the pons and dorsal and medial to it., [4] [5]
The periaqueductal gray (PAG), an area of the brain involved in mediating analgesia, sends efferent stimuli to the nucleus raphe magnus when stimulated by opioids (endogenous or otherwise); electrical stimulation of the PAG as well as administration of opioid agonists to the PAG or nucleus raphe magnus produces analgesia; the antinociceptic ...
These nuclei interact with almost every pertinent portion of the brain, but only a few of them have specifically independent interaction. These select nuclei are discussed as follows. Overall, the caudal raphe nuclei, including the nucleus raphe magnus, nucleus raphe pallidus and nucleus raphe obscurus, all project towards the spinal cord and ...
The tegmentum area includes various different structures, such as the rostral end of the reticular formation, several nuclei controlling eye movements, the periaqueductal gray matter, the red nucleus, the substantia nigra, and the ventral tegmental area. [3] The tegmentum is the location of several cranial nerve nuclei. The nuclei of CN III and ...
Most famous parts of the brain highlighted in different colours The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate.
The entorhinal cortex (EC) is an area of the brain's allocortex, located in the medial temporal lobe, whose functions include being a widespread network hub for memory, navigation, and the perception of time. [1] The EC is the main interface between the hippocampus and neocortex.
This area is known as perirhinal area 35. It is a subdivision of the cytoarchitecturally defined hippocampal region of the cerebral cortex. In the human it is located along the rhinal sulcus. Cytoarchitectually it is bounded medially by the entorhinal area 28 and laterally by the ectorhinal area 36 (H).
