The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. [1] It is located between the ventricular system and distinctive basal or ventral structures at each level. It forms the floor of the midbrain (mesencephalon) whereas the tectum forms the ceiling. [2] It is a multisynaptic network of neurons ...
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and other dopamine ...
The reticular formation is a set of interconnected nuclei in the brainstem that spans from the lower end of the medulla oblongata to the upper end of the midbrain. [2] The neurons of the reticular formation make up a complex set of neural networks in the core of the brainstem. [3] It is not anatomically well defined, because it includes neurons ...
The midbrain tegmentum is also an important part of the dopaminergic system which is essential for feelings of reward and pleasure. Two regions in the midbrain tegmentum are of particular interest. The first one is the substantia nigra which is an important part of the nigrostriatal pathway. This pathway serves to coordinate motor movements and ...
Carol Susan Dweck (born October 17, 1946) is an American psychologist. She holds the Lewis and Virginia Eaton Professorship of Psychology at Stanford University. Dweck is known for her work on motivation and mindset. She was on the faculty at the University of Illinois, Harvard, and Columbia before joining the Stanford University faculty in ...
The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. [ 1 ] The pathway connects the ventral tegmental area in the midbrain to the ventral striatum of the basal ganglia in the forebrain. The ventral striatum includes the nucleus accumbens and the olfactory tubercle.
The central tegmental tract[1] is a structure in the midbrain and pons. It contains: ascending second-order axons projecting from the gustatory nucleus [citation needed] of nucleus solitarius [2]: 112 to the ventral posteromedial nucleus [2]: 473 of thalamus [2]: 112 (third-order neurons in turn project to the gustatory cortex) descending ...
The pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons. The pontine tegmentum is all the material dorsal from the basilar pons to the fourth ventricle. Along with the dorsal surface of the medulla oblongata, it forms part of ...
