الدماغ المتوسط (باللاتينية: mesencephalon) أو (بالإنجليزية: Midbrain) هو قسم من أقسام الجهاز العصبي المركزي والذي يرتبط بالرؤية والسمع والتحكم الحركي والنوم واليقظة وتنظيم درجة حرارة الجسم. وهو أقصر أجزاء جذع الدماغ ويقع بين. The midbrain (Latin: mesencephalon) is the most caudal part of the brainstem.The midbrain connects the pons and cerebellum with the forebrain. The midbrain's structures and connections are associated with hearing, vision, motor control, alertness, temperature sensation, sleep, and wakefulness.. Anatomy of the midbrain. The midbrain is the shortest part of the brainstem, being less than 2 cm. The brainstem is the most inferior and primitive part of the brain, continuous caudally with the spinal cord and rostrally with the diencephalon (thalamus, hypothalamus, epithalamus, and subthalamus) ( 1 ). The named parts, from cranial to caudal, comprise the midbrain (mesencephalon), pons (metencephalon), and medulla oblongata (myelencephalon) midbrain shows the area involved in Benedikt syndrome (blue). Figure 6. Axial T2-weighted image (3 T) at the level of the midbrain shows the area involved in Claude syndrome (blue). Claude Syndrome.—Claude syndrome is caused by infarction of the dorsomedial aspect of the midbrain due to occlusion of the small perforat
The midbrain is one of the three subdivisions of the brainstem; it is the most rostral of these subdivisions, or the one that is closest to the top of the brainstem. The midbrain connects the brainstem to the diencephalon at a location sometimes called the midbrain-diencephalon junction.. What is the midbrain and what does it do? Although it is a relatively small section of neural tissue, the. Epidemiology. Although many different brainstem stroke syndromes have been classically described, the majority appear extremely rarely in the literature and are mainly for historical interest only 1.The most common brainstem stroke syndrome seems to be the lateral medullary syndrome (Wallenberg syndrome) 1.. Clinical presentatio Here, we performed high-throughput and circuit-specific single-cell transcriptomic analyses of neurons in the superior colliculus (SC), a midbrain structure implicated in early sensorimotor transformation. We found that SC neurons in distinct laminae expressed discrete marker genes The midbrain represents the uppermost portion of the brainstem, containing numerous important nuclei and white matter tracts, most of which are involved in motor control, as well as the auditory and visual pathways. Notable midbrain nuclei include the superior and inferior colliculus nuclei, red nucleus, substantia nigra, oculomotor nuclear complex, and trochlear nucleus

The SC of the midbrain is a classical model for the study of early sensorimotor transformation related to sensory-triggered innate behaviors (fish [Bianco and Engert, 2015]; rodents [Dean et al., 1989]; primates [Sparks, 1986]) Dopamine (DA) is an essential neurotransmitter in the brain, controlling motor behaviors, cognition, memory, and reward. The major group of neurons releasing DA is situated in the ventral midbrain. สมองส่วนกลาง (Midbrain) - เป็นสมองที่ต่อจากสมองส่วนหน้า เป็นสถานีรับส่งประสาท ระหว่างสมองส่วนหน้ากับส่วนท้ายและส่วนหน้ากับ. The tectum (Latin: roof) is a region of the brain, specifically the dorsal part of the mesencephalon (midbrain). This is contrasted with the tegmentum, which refers to the region ventral to the ventricular system.It is responsible for auditory and visual reflexes. It is derived in embryonic development from the alar plate of the neural tube
Midbrain. It includes the nuclei of the 3rd (oculomotor), 4th (trochlear) and 5th (trigeminal) cranial nerves. The midbrain is the smallest section of the brainstem and is situated just above the pons. It is traversed by the cerebral aqueduct. The part dorsal to the aqueduct is termed the tectum and is composed of 4 surface levels-the corpora. mesencephalon [mes″en-sef´ah-lon] 1. the short part of the brainstem just above the pons; it contains the nerve pathways between the cerebral hemispheres and the medulla oblongata, as well as nuclei (relay stations or centers) of the third and fourth cranial nerves.

Human midbrain dopamine (DA) neurons are a heterogeneous group of cells that share a common neurotransmitter phenotype and are in close anatomical proximity but display different functions, sensitivity to degeneration, and axonal innervation targets. The A9 DA neuron subtype controls motor function and is primarily degenerated in Parkinson's disease (PD), whereas A10 neurons are largely. Induction of midbrain FP cells is a prerequisite for generating midbrain DA neurons. FP cells express FoxA2 and high concentrations of SHH can efficiently induce hPSCs to FoxA2-expressing cells [ 20 , 46 ], as also shown in our present study Midbrain dopamine (DA) neurons are implicated in many of the psychological factors and disorders (6, 8, 11) associated with changes in time estimation. Midbrain DA neurons also encode reward prediction errors (RPEs) (12-15), an important teaching signal in reinforcement learning Dopamine (DA) dysregulation, which can be traced to a common neural origin in the midbrain, manifests in striatal hyperdopaminergia, which is linked to psychosis, and cortical hypodopaminergia, which contributes to cognitive deficits [1, 2].Importantly, gamma aminobutyric acid (GABA) neurotransmission controls activity of dopamine neurons within the midbrain [3,4,5,6], yet the status of the.

Most functional studies in the visual system have focused on the cortical representation of the geniculo-striate pathway that links the retina to the cortex. The parallel collicular pathway is believed to sparsely project throughout the visual cortex and have a modulatory role on cortical responses to visual stimuli. Beltramo and Scanziani found a visual cortical area that is entirely. Two further aspects of midbrain firing seen in electrophysiological data may be relevant to the current fMRI findings. First, midbrain neurons display generalization, in which they fire to stimuli that are similar to those predictive of reward (Tobler et al., 2005; Shohamy and Wagner, 2008). It is a testable hypothesis that problem gamblers. Furthermore, analysis using dopaminergic progenitor cell lines and midbrain slice cultures revealed that the neuroprotective effects of Atl and A2 are mediated by activation of Nrf2, a. We utilized human midbrain-like organoids (hMLOs) generated from human pluripotent stem cells (hPSCs) carrying glucocerebrosidase gene (GBA1) and α-synuclein (SNCA) perturbations to investigate genotype-to-phenotype relationships in Parkinson's disease, with the particular aim of recapitulating α-syn and Lewy body-related pathologies and.
