Hirotaro Narabayashi
was a prominent Japanese neurosurgeon. He was born in Kobe into a long line of physicians originally from Nagasaki. He was a descendant of Chinzan Narabayashi who had studied Western medicine with Dutch physicians at Dejima in the 17th century. He received his medical degree from the Tokyo University School of Medicine in 1946 and his Ph.D. from Tokyo University in 1955. In the same year, he was appointed Associate Professor, Department of Neuropsychiatry, at the Juntendo University School of Medicine in Tokyo. He was promoted to Full Professor in 1964. From 1968 to 1988, he was Professor and Chairman of the Department of Neurology at the Juntendo University School of Medicine. Although trained originally as a neuropsychiatrist, he is best known for his pioneering work in stereotactic surgery, especially the surgical treatment of Parkinson's disease. In 1949 he constructed a stereotaxic apparatus based on drawings of that constructed in the United States by Victor Horsley and R ...

It is located in Kansai region, which makes up the southern side of the main island of Honshū, on the north shore of Osaka Bay. It is part of the Keihanshin metropolitan area along with Osaka and Kyoto. The Kobe city centre is located about west of Osaka and southwest of Kyoto. The earliest written records regarding the region come from the '' Nihon Shoki'', which describes the founding of the Ikuta Shrine by Empress Jingū in AD 201.Ikuta Shrine official website

Athetoid
Athetosis is a symptom characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue. Movements typical of athetosis are sometimes called ''athetoid'' movements. Lesions to the brain are most often the direct cause of the symptoms, particularly to the corpus striatum. This symptom does not occur alone and is often accompanied by the symptoms of cerebral palsy, as it is often a result of this physical disability. Treatments for athetosis are not very effective, and in most cases are simply aimed at managing the uncontrollable movement, rather than the cause itself. Signs and symptoms Athetosis can vary from mild to severe motor dysfunction; it is generally characterized by unbalanced, involuntary movements of muscle and a difficulty maintaining a symmetrical posture. The associated motor dysfunction can be restricted to a part of the body or present throughout the body, depending on the indiv ...

Fidel Castro
Fidel Alejandro Castro Ruz (; ; 13 August 1926 – 25 November 2016) was a Cuban revolutionary and politician who was the leader of Cuba from 1959 to 2008, serving as the prime minister of Cuba from 1959 to 1976 and president from 1976 to 2008. Ideologically a Marxist–Leninist and Cuban nationalist, he also served as the first secretary of the Communist Party of Cuba from 1961 until 2011. Under his administration, Cuba became a one-party communist state; industry and business were nationalized, and state socialist reforms were implemented throughout society. Born in Birán, the son of a wealthy Spanish farmer, Castro adopted leftist and anti-imperialist ideas while studying law at the University of Havana. After participating in rebellions against right-wing governments in the Dominican Republic and Colombia, he planned the overthrow of Cuban President Fulgencio Batista, launching a failed attack on the Moncada Barracks in 1953. After a year's imprisonment, Castro travel ...

Pallidum
The globus pallidus (GP), also known as paleostriatum or dorsal pallidum, is a subcortical structure of the brain. It consists of two adjacent segments, one external, known in rodents simply as the globus pallidus, and one internal, known in rodents as the entopeduncular nucleus. It is part of the telencephalon, but retains close functional ties with the subthalamus in the diencephalon – both of which are part of the extrapyramidal motor system. The globus pallidus is a major component of the basal ganglia, with principal inputs from the striatum, and principal direct outputs to the thalamus and the substantia nigra. The latter is made up of similar neuronal elements, has similar afferents from the striatum, similar projections to the thalamus, and has a similar synaptology. Neither receives direct cortical afferents, and both receive substantial additional inputs from the intralaminar thalamus. Globus pallidus is Latin for "pale globe". Structure Pallidal nuclei are made u ...

Pallidotomy
Pallidotomy is a neurosurgical procedure. It is used to treat Parkinson's disease and some other conditions, often as an alternative to deep brain stimulation. It involves placing a tiny electrical probe in the globus pallidus, one of the basal ganglia of the brain, to damage it. Unilateral pallidotomy can cause side effects including problems with language learning, visuospatial constructional ability, and executive functions. Bilateral pallidotomy is not effective, with many severe side effects. Uses Rationale The internal globus pallidus can be regarded as an "output structure" of the basal ganglia. It processes input from nucleus accumbens and the striatum, and sends input to the cerebral cortex via the thalamus. It is critical for the functioning of the basal ganglia. Parkinson's disease Pallidotomy is an alternative to deep brain stimulation for the treatment of the involuntary movements known as dyskinesias which can become a problem in people with Parkinson's disea ...

Nagasaki, Nagasaki
is the capital and the largest city of Nagasaki Prefecture on the island of Kyushu in Japan. It became the sole port used for trade with the Portuguese and Dutch during the 16th through 19th centuries. The Hidden Christian Sites in the Nagasaki Region have been recognized and included in the UNESCO World Heritage List. Part of Nagasaki was home to a major Imperial Japanese Navy base during the First Sino-Japanese War and Russo-Japanese War. Near the end of World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack (at 11:02 am, August 9, 1945 'Japan Standard Time (UTC+9)'). , the city has an estimated population of 407,624 and a population density of 1,004 people per km2. The total area is . History Nagasaki as a Jesuit port of call The first contact with Portuguese explorers occurred in 1543. An early visitor was Fernão Mendes Pinto, who came from Sagres on ...

Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms usually emerge slowly, and as the disease worsens, non-motor symptoms become more common. The most obvious early symptoms are tremor, rigidity, slowness of movement, and difficulty with walking. Cognitive and behavioral problems may also occur with depression, anxiety, and apathy occurring in many people with PD. Parkinson's disease dementia becomes common in the advanced stages of the disease. Those with Parkinson's can also have problems with their sleep and sensory systems. The motor symptoms of the disease result from the death of cells in the substantia nigra, a region of the midbrain, leading to a dopamine deficit. The cause of this cell death is poorly understood, but involves the build-up of misfolded proteins into Lewy bodies in the neurons. Collectively, the main motor symptoms are also known as ...
