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.
"Reptilian complex" (also known as the "R-complex", "reptilian brain" or "lizard brain") was the name MacLean gave to the basal ganglia, structures derived from the floor of the forebrain during development. The term derives from the idea that comparative neuroanatomists once believed that the forebrains of reptiles and birds were dominated by ...
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 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.
Triune mind, triune brain is a theoretical model developed by Canadian Buddhist scholar Suwanda H. J. Sugunasiri. It follows upon his clarification of the three terms used by the Buddha for consciousness, namely, Mano , Citta and Viññāṇa as can be seen in his work on the triune mind . [ 1 ]
Evidence for the role of astrocytes in the integration and processing of synaptic integration presents itself in a number of ways: Astrocytes are excitable cells: In response to stimuli from any of the three components of the tripartite synapse, astrocytes are capable of producing transient changes in their intracellular calcium concentrations through release of calcium stores from the ...

The three subdivisions are an opercular part, a triangular part, and an orbital part. These divisions are marked by two rami arising from the lateral sulcus. [3] The ascending ramus separates the opercular and triangular parts. [4] The anterior (horizontal) ramus separates the triangular and orbital parts. [5]
