The three major branches of the trigeminal nerve—the ophthalmic nerve (V 1), the maxillary nerve (V 2) and the mandibular nerve (V 3)—converge on the trigeminal ganglion (also called the semilunar ganglion or gasserian ganglion), located within Meckel's cave and containing the cell bodies of incoming sensory-nerve fibers.
The entorhinal cortex (EC) is a structure in the brain located in the medial temporal lobe.The EC is composed of six distinct layers. The superficial (outer) layers, which include layers I through III, are mainly input layers that receive signals from other parts of the EC, but also project to hippocampal structures via the perforant path.
Since the 1970s, the concept of the triune brain has been subject to criticism in evolutionary and developmental neuroscience [1] and is regarded as a myth. [2] Although it overlaps in some respects with contemporary understanding of the brain, [ 3 ] the triune brain hypothesis is no longer espoused by comparative neuroscientists in the post ...
The trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
The sensory trigeminal nerve nuclei are the largest of the cranial nerve nuclei, and extend through the whole of the midbrain, pons and medulla, and into the upper cervical spinal cord.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .

This concept does not represent the process for transmitting signals between neurons in the brain beyond the developmental stage. In collaboration with the University of Rochester’s Institute of Optics, Nedergaard and her team had developed a new 2-photon microscope that had allowed researchers to observe glia activity in the living brain ...
