By around 12 weeks of development the cerebral hemispheres, diencephalon, mesencephalon
, cerebellum, pons, medulla oblongata and spinal cord have formed (Martini 2004).
The key components are the basal ganglia (the dorsal and ventral striatum, and dorsal and ventral pallidum); the dopaminergic fibers that ascend from the mesencephalon
(substantia nigra and nucleus A10 in the ventral tegmental area) to innervate the basal ganglia; thalamic nuclei closely linked to the basal ganglia; and similarly, neocortical areas (motor, sensorimotor, and prefrontal cortex) closely linked to the basal ganglia".
Instead, a brainstem reflex category was created to assess the function of the mesencephalon
, pons, and medulla.
Faucheux BA, Bonnet AM, Agid Y, Hirsch EC Blood vessels change in the mesencephalon
of patients with Parkinson's disease.
remains a single vesicle and retains the name mesencephalon
At HH stage 10, Mnb mRNA was detected at different levels of the closed neural tube: the prospective prosencephalon, mesencephalon
, rhombencephalon, and spinal cord (Figure 1i).
Once opioids stimulate [mu] receptors located in the mesencephalon
and medulla, GABAergic inhibition is reduced, and the descending fibers are now free to act on T cells that carry ascending nociceptive stimuli through the spinal cord.
Moreover, the upper brain stem may be subjected to strains greater than would otherwise be expected because of the particular anatomy of that region, which is characterized by the relatively small attachment of the mesencephalon
to the large masses of the cerebral hemispheres .
Weber and Pert found a "dramatic" drop in killer cell performance when rats got morphine delivered to a brain region known as the peri-aqueductal gray matter of the mesencephalon
This involvement includes the monoaminergic regions located centrally in the mesencephalon
and substantia nigra (6, 11, 28).
Metabonomics based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was used to profile the metabolic fingerprints of mesencephalon
obtained from 1-Methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine Hydrochloride (MPTP-HCI)-induced PD mice model with and without EAS treatment.
