- Shute and Lewis first revealed the presence of a cholinergic component of the RAS, composed of two ascending mesopontine tegmental pathways rostrally situated between the mesencephalon and the centrum semiovale ( semioval center ).
- Concentration gradients of fibroblast growth factor 8 ( FGF8 ) and Wingless-Type MMTV Integration Site Family, Member 1 ( Wnt1 ) control expression of Pax2 during development of the Mesencephalon, or midbrain.
- The midbrain ( or mesencephalon ) is situated above and rostral to the pons, and includes nuclei linking distinct parts of the motor system, among others the cerebellum, the basal ganglia and both cerebral hemispheres.
- With increasing pressure and progression of the hernia there will be distortion of the brainstem leading to Duret hemorrhages ( tearing of small vessels in the parenchyma ) in the median and paramedian zones of the mesencephalon and pons.
- Pax-7 plays a role in neural crest development and gastrulation, and it is an important factor in the expression of neural crest markers such as mesencephalon, nasal cavity, nasal epithelium, nasal capsule and pons.
- 1-The archipallium or primitive ( " reptilian " ) brain, comprising the structures of the brain stem-medulla, pons, cerebellum, mesencephalon, the oldest basal nuclei-the globus pallidus and the olfactory bulbs.
- These are the telencephalon, diencephalon, mesencephalon, metencephalon, and myelencephalon which later become the lateral ventricles, third ventricles, aqueduct, and upper and lower parts of the fourth ventricle from the telencephalon to the myelencephalon, during adulthood.
- Wohlfart ( 1961 ) hypothesized that klazomania is caused by an irritating lesion in the mesencephalon and a malfunction in the control of the motor circuit from the substantia nigra in the mesencephalon to the globus pallidus in the striatum ( mesostraital pathway ).

Ommaya defined four steps in the evolution of consciousness . 1 ) reflex and avoidance reactions; 2 ) sensory inputs merged with multisensory neurons in the mesencephalon; 3 ) interactions formed between sensory and limbic systems and memory; and 4 ) reinforcement of thalamic neural centers which relays information between sensory and motor centers.
- The cephalic end of the neural groove exhibits several dilatations, which, when the tube is closed, assume the form of three vesicles; these constitute the three primary cerebral vesicles, and correspond respectively to the future fore-brain ( prosencephalon ), mid-brain ( mesencephalon ), and hind-brain ( rhombencephalon ).
- The "'substantia nigra "'is a brain structure located in the mesencephalon ( midbrain ) that plays an important role in movement . " Substantia nigra " is Latin for " black substance ", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons.
- The anterior ( or'rostral') portion of the neural tube initially differentiates into three brain vesicles ( pockets ) : the prosencephalon at the front, the mesencephalon, and, between the mesencephalon and the spinal cord, the rhombencephalon . ( By six weeks in the human embryo ) the prosencephalon then divides further into the telencephalon and diencephalon; and the rhombencephalon divides into the metencephalon and myelencephalon.
