The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found primarily in the Neotropical realm. Genera
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 ...
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.
The piriform cortex occupies a greater proportion of the overall brain and of the telencephalic brains of insectivores than in primates. The piriform cortex continues to occupy a consistent albeit small and declining proportion of the increasingly large telencephalon in the most recent primate species while the volume of the olfactory bulb ...
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 ...
The pulvinar nuclei or nuclei of the pulvinar (nuclei pulvinares) are the nuclei (cell bodies of neurons) located in the thalamus (a part of the vertebrate brain). [1] As a group they make up the collection called the pulvinar of the thalamus (pulvinar thalami), usually just called the pulvinar.
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).
