Robert Wartenberg
Robert Wartenberg (June 19, 1887 – November 16, 1956) was a clinical neurologist and professor. Born in the then-Russian Empire, he attended university and established his career in Germany. As a Jew, he was fired from his position as the University of Freiburg's Clinical Department of Neurology during the Nazi regime. He immigrated to the US, settling in San Francisco and teaching at the University of California in San Francisco. He authored more than 150 papers and four books and made many significant discoveries in the area of clinical signs of neurological conditions. He continues to be commemorated by the American Academy of Neurology's annual Robert Wartenberg Lecture and by many eponyms in the field of neurology. Early life and education Wartenberg was born in 1887 in Grodno, Belarus, then in the Russian Empire. He studied at the Universities of Kiel, Munich, and Freiburg eventually graduating magna cum laude from the University of Rostock, Germany in 1919. He w ...

Grodno
Grodno, or Hrodna, is a city in western Belarus. It is one of the oldest cities in Belarus. The city is located on the Neman, Neman River, from Minsk, about from the Belarus–Poland border, border with Poland, and from the Belarus–Lithuania border, border with Lithuania. Grodno serves as the administrative center of Grodno Region and Grodno District, though it is administratively separated from the district. the city has a population of 363,718. The modern city of Grodno, founded in 1127, originated as a small fortress and trading outpost on the border of the Baltic tribal union of the Yotvingians. It was also a home to the Dregoviches Slavic tribe. It was a significant city in Black Ruthenia and later part of the Grand Duchy of Lithuania, which joined the Polish-Lithuanian Union in 1385. Grodno faced numerous invasions, most notably by the Teutonic Knights. The city was a key trade, commerce, and cultural center in the Polish-Lithuanian Commonwealth, and one of its roya ...

Eponym
An eponym is a noun after which or for which someone or something is, or is believed to be, named. Adjectives derived from the word ''eponym'' include ''eponymous'' and ''eponymic''. Eponyms are commonly used for time periods, places, innovations, biological nomenclature, astronomical objects, works of art and media, and tribal names. Various orthographic conventions are used for eponyms. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. ''Eponym'' may refer to a person or, less commonly, a place or thing for which someone or something is, or is believed to be, named. ''Eponym'' may also refer to someone or something named after, or believed to be named after, a person or, less commonly, a place or thing. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era, but the Elizabethan ...

Cheiralgia Paresthetica
Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand. Symptoms include numbness, tingling, burning or pain. Since the nerve branch is sensory there is no motor impairment. It may be distinguished from de Quervain syndrome because it is not dependent on motion of the hand or fingers. Cause The most common cause is thought to be constriction of the wrist, as with a bracelet or watchband (hence reference to "wristwatch neuropathy"). It is especially associated with the use of handcuffs and is therefore commonly referred to as handcuff neuropathy. Other injuries or surgery in the wrist area can also lead to symptoms, including surgery for other syndromes such as de Que ...

Achilles Tendon
The Achilles tendon or heel cord, also known as the calcaneal tendon, is a tendon at the back of the lower leg, and is the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle joint, and (except the soleus) flexion at the knee. Abnormalities of the Achilles tendon include inflammation ( Achilles tendinitis), degeneration, rupture, and becoming embedded with cholesterol deposits ( xanthomas). The Achilles tendon was named in 1693 after the Greek hero Achilles. History The oldest-known written record of the tendon being named after Achilles is in 1693 by the Flemish/Dutch anatomist Philip Verheyen. In his widely used text he described the tendon's location and said that it was commonly called "the cord of Achilles." The tendon has been described as early as the time of Hippocrates, who described it as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Motor Neurons
Lower motor neurons (LMNs) are motor neurons located in either the anterior grey column, anterior nerve roots (spinal lower motor neurons) or the cranial nerve nuclei of the brainstem and cranial nerves with motor function (cranial nerve lower motor neurons). Many voluntary movements rely on spinal lower motor neurons, which innervate skeletal muscle fibers and act as a link between upper motor neurons and muscles. Cranial nerve lower motor neurons also control some voluntary movements of the eyes, face and tongue, and contribute to chewing, swallowing and vocalization. Damage to lower motor neurons often leads to hypotonia, hyporeflexia, flaccid paralysis as well as muscle atrophy and fasciculations. Classification Lower motor neurons are classified based on the type of muscle fiber they innervate: * Alpha motor neurons (α-MNs) innervate extrafusal muscle fibers, the most numerous type of muscle fiber and the one involved in muscle contraction. * Beta motor neurons (β-MN ...

Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease primarily of the central nervous system, affecting both motor system, motor and non-motor systems. Symptoms typically develop gradually and non-motor issues become more prevalent as the disease progresses. The motor symptoms are collectively called parkinsonism and include tremors, bradykinesia, spasticity, rigidity as well as postural instability (i.e., difficulty maintaining balance). Non-motor symptoms develop later in the disease and include behavior change (individual), behavioral changes or mental disorder, neuropsychiatric problems such as sleep abnormalities, psychosis, anosmia, and mood swings. Most Parkinson's disease cases are idiopathic disease, idiopathic, though contributing factors have been identified. Pathophysiology involves progressive nerve cell death, degeneration of nerve cells in the substantia nigra, a midbrain region that provides dopamine to the basal ganglia, a system invo ...

Myelography
Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray projections. Today, myelography has largely been replaced by the use of MRI scans, although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT rather than X-ray projections. Types Cervical myelography This procedure is used to look for the level of where spinal cord disease occurs or compression of the spinal cord at the neck region for those who are unable or unwilling to undergone MRI scan of the spine. Lumbar myelography This procedure is to look for the level of spinal cord disease such as lumbar nerve root compression, cauda equina syndrome, conus medullaris lesions, and spinal ...

Electroencephalography
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignal, bio signals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the 10–20 system (EEG), International 10–20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called Electrocorticography, "intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG, quantitative EEG analysis. Voltage fluctuations measured by the EEG bioamplifier, bio amplifier and electrodes allow the evaluation of normal Brain activity and meditation, brain activity. As the electrical activity monitored by EEG originates in neurons in the underlying Huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festschrift
In academia, a ''Festschrift'' (; plural, ''Festschriften'' ) is a book honoring a respected person, especially an academic, and presented during their lifetime. It generally takes the form of an edited volume, containing contributions from the honoree's colleagues, former pupils, and friends. ''Festschriften'' are often titled something like ''Essays in Honour of...'' or ''Essays Presented to... .'' Terminology The term, borrowed from German, and literally meaning "celebration writing" (cognate with ''feast-script''), might be translated as "celebration publication" or "celebratory (piece of) writing". An alternative Latin term is (literally: "book of friends"). A comparable book presented posthumously is sometimes called a (, "memorial publication"), but this term is much rarer in English. A ''Festschrift'' compiled and published by electronic means on the internet is called a (pronounced either or ), a term coined by the editors of the late Boris Marshak's , ''Eran ud Ane ...
