Peter Huttenlocher
Peter Richard Huttenlocher (23 February 1931 – 15 August 2013) was a German-American pediatric neurologist and neuroscientist who discovered how the brain develops in children. He is considered to be one of the fathers of developmental cognitive neuroscience. Work He discovered that synapses are created in the first few months of a child's development, and then "pruned", by examining the brains of about 50 people, mostly infants and young children who had died unexpectedly, but also a few adults, one of them age 90. Using an electron microscope to count image samples of material, and then manually counting the synapses, he showed that synaptic density was low at birth, about 2,500 connections per neuron. It increased rapidly to levels 50 to 60 percent above adult levels, and then gradually declined, falling to typical adult values. He had originally intended to study defective parts of the brain, but found that: "Paradoxically, in our early studies, the findings in the normal p ...

Lahnstein
Lahnstein () is a ''verband''-free town of Rhein-Lahn-Kreis in Rhineland-Palatinate, Germany. It is situated at the confluence of the Lahn with the Rhine, approximately south of Koblenz. Lahnstein was created in 1969 by the merger of the previously independent towns of Oberlahnstein (or Upper Lahnstein) on the south side of the Lahn (above the river mouth) and Niederlahnstein on the north side (below the river mouth). In 2020, it had a population of 18,030. Situated on the heights of the foothills of the Westerwald and the Taunus, Lahnstein is considered a fresh-air spa city with spa facilities and thermal baths. It is also the seat of a district court. In religious affairs, it is assigned to the Roman Catholic Diocese of Limburg and to the Evangelical Church in Hesse and Nassau. Because of its strategic importance on the Rhine, Lahnstein was heavily fortified. Many old gates and towers still demonstrate its importance in the Middle Ages. Lahneck Castle, situated high above Ober ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summa Cum Laude
Latin honors are a system of Latin phrases used in some colleges and universities to indicate the level of distinction with which an academic degree has been earned. The system is primarily used in the United States. It is also used in some Southeastern Asian countries with European colonial history, such as Indonesia and the Philippines, although sometimes translations of these phrases are used instead of the Latin originals. The honors distinction should not be confused with the honors degrees offered in some countries, or with honorary degrees. The system usually has three levels of honor: ''cum laude'', ''magna cum laude'', and ''summa cum laude''. Generally, a college or university's regulations set out definite criteria a student must meet to obtain a given honor. For example, the student might be required to achieve a specific grade point average, submit an honors thesis for evaluation, be part of an honors program, or graduate early. Each school sets its own standards. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system.

Flute
The flute is a family of classical music instrument in the woodwind group. Like all woodwinds, flutes are aerophones, meaning they make sound by vibrating a column of air. However, unlike woodwind instruments with reeds, a flute is a reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones. A musician who plays the flute is called a flautist or flutist. Flutes are the earliest known identifiable musical instruments, as paleolithic examples with hand-bored holes have been found. A number of flutes dating to about 53,000 to 45,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.. Citation on p. 248. * While the oldest flutes currently known were found in Europe, Asia, too, has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The National Institutes of Health, commonly referred to as NIH (with each letter pronounced individually), is the primary agency of the United States government responsible for biomedical and public health research. It was founded in the late 1880s and is now part of the United States Department of Health and Human Services. The majority of NIH facilities are located in Bethesda, Maryland, and other nearby suburbs of the Washington metropolitan area, with other primary facilities in the Research Triangle Park in North Carolina and smaller satellite facilities located around the United States.
