As this process occurs, the choroid plexus develops from blood vessels that invade the ventricles from the diencephalon and the myelencephalon.
Numerous sites of dysfunction have been speculated, from the upper brain stem and diencephalon (Bullard), brain stem (Cartlidge & Shaw, 1981), orbital frontal cortex (Strum, 2002), and, more specifically, the anterior hypothalamus or medulla (Boeve et al.
At 29 hours, the optic vesicle, which later gives rise to the optic cup, was visible as an extension of the diencephalon.
The target is presented to one eye and the information is conveyed to two regions of the brain, the optic tectum and the nucleus rostrolateralis in the diencephalon.
These impulses, emotions, and feelings are located in the diencephalon, which is well developed in many other species of animals, especially mammals and birds.
30 The device is designed for non-drug treatment of diencephalon disorders, pain syndrome of different ethiology, and localization.
Destruction of a critical array of neurons within the "whole" brain (hemispheres, diencephalon, and brain stem) is necessary for death because: 1) the vital functions of respiration and control of circulation are subserved by the brain stem; 2) the critical integrative functions are subserved by both the brain stem and hypothalamus; and 3) the wakefulness component of consciousness is subserved by the brain stem and the awareness component of consciousness by the thalamus and cerebral cortex.
The diencephalon at the top of the brain stem which evolved four hundred million years ago is the seat of appetite; the limbic system or "reptile brain" which is the seat of aggressive behavior (spiritedness), evolved as a quasi-separate organ added onto the top of the brain stem three hundred million years ago; and two million years ago the "rational" part of the brain, the cerebral cortex, evolved as another organ grafted on top of the rest of the human brain.

It is expressed in the nuclei of thyroid follicular cells, certain lung cells (mainly Clara cells and type II pneumocytes), and cells in the diencephalon area of the brain.
At necropsy, the cerebellum, brainstem, and diencephalon appeared normal in shape and volume (Figure).
Analysing the MRI images, the researchers observed that in patients with anorexia compared with healthy subjects, a certain network pathway between the cortex and the diencephalon is less activated.
