The drug rotigotine belongs to the group of non-ergoline dopamine agonists and is used in the therapy of restless legs syndrome or Parkinson’s disease. What is rotigotine? Rotigotine is a so-called aminotetroline and tiophene derivative that is very similar to dopamine. It is liptophilic and has an extremely low molecular weight, so it is well … Rotigotine: Effects, Uses & Risks
Optic chiasm is the name given to a junction of the optic nerve. At this section, the nerve fibers of the nasal halves of the retina cross. What is the optic chiasm? The optic chiasm is also known as the optic nerve junction and forms an important part of the visual pathway. In it, the … Optic Chiasm: Structure, Function & Diseases
The ansa cervicalis (profunda) or cervical nerve loop lies beneath the sternocleidomastoid muscle and contains fibers from cervical spinal cord segments C1 to C3. It is responsible for controlling the lower hyoid (infrahyoid) muscles and can lead to the development of dysphagia when lesioned. What is the ansa cervicalis? The ansa cervicalis is a loop … Ansa Cervicalis: Structure, Function & Diseases
The fornix cerebri is part of the limbic system and forms a curved projection pathway between the mamillary bodies (corpora mamillara) and the hippocampus. The fornix cerebri can be divided into four areas and consists of fibers of the olfactory pathway. It is associated with memory retrieval, which is why damage to the fornix cerebri … Fornix Cerebri: Structure, Function & Diseases
Auditory cortex In the occipital lobe, the tremendously complex sense of sight (visual sense) is cortically represented. The visual pathway starts at the sensory cells of the retina and runs as the II cranial nerve (optic nerve) via several intermediate stations to the primary visual cortex (visual cortex). This represents, in the simple representation of … Auditory cortex | Cerebrum
Limbic system If a knife is inserted into the interhemispheric fissure (fissura longitudinalis cerebri) and cut in the direction of the brain stem (median section), numerous structures are visible which are attributed to the limbic system (limbic). It deals with emotions as well as with instinctive and intellectual behavior. Rather primitive achievements such as affective … Limbic system | Cerebrum
Basal Ganglia Finally, we now cut the cerebrum not with the length of the interhemispheric cleft, but rather in the middle of it transversely parallel to the forehead (frontal cut). In this incision, too, it is noticeable that some grey matter is embedded in the white matter of the cerebrum, which therefore does not belong … Basal Ganglia | Cerebrum
Common diseases Neurodegenerative diseases such as Parkinson’s disease, Huntington’s disease, Alzheimer’s disease, as well as strokes, headaches, epilepsy and brain tumors occur comparatively frequently. In our modern society, depressions, psychoses such as schizophrenia and addictions are on the rise. Other diseases or consequences of diseases of the cerebrum are Multiple Sclerosis (MS) Amyothrophic lateral sclerosis … Common diseases | Cerebrum
Synonyms in the broadest sense Telencephalon, cerebrum, endbrain. Introduction The cerebrum with its enormous mass grows in humans the diencephalon, parts of the brain stem and cerebellum. As a total product, amazing abilities such as logical thinking, the own consciousness, emotions, memory and various learning processes develop. Also of highly practical importance are precise movements … Cerebrum
Smell bark At the base of the frontal lobe there are also phylogenetic components (olfactory cortex, paleocortex and archicortex), which are dedicated to the sense of smell (olfactory sense). Presumably, the olfactory sensations come into consciousness in the so-called “primary olfactory cortex” (prepiriform cortex, which is also located to a lesser extent in the temporal … Smell bark | Cerebrum
The human mesolimbic system is called the positive reward center. It is part of the central nervous system. It is located in the cerebrum of the human organism. What is the mesolimbic system? The mesolimbic system is also known as the area tegmentalis ventralis. It is composed of the nucleus accumbens and parts of the … Mesolimbic System: Structure, Function & Diseases
Synonyms Medical: Meninx encephali Definition The meninges are a connective tissue layer that surrounds the brain. In the spinal canal, it merges into the spinal cord skin. The human being has three meninges. From outside to inside, these are the hard meninges (dura mater or leptomeninx encephali), and the soft meninges (pia mater or pachymeninx … Meninges
