Cystoscopy, or also called bladder endoscopy, is a procedure that allows to examine the lining of your bladder and the tube that carries urine out of your body. The cystoscope is a hollow tube equipped with a lens and it is inserted into your urethra and slowly advanced into your bladder. Credits: Nucleus Medical Media

Ataxia is a non-specific clinical manifestation implying dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum. It is a neurological sign consisting of lack of voluntary coordination of muscle movements that includes gait abnormality.

Magic mushrooms have been used ritually by the native people of Mesoamerica for hundreds, if not thousands, of years. In the 1950s, R. Gordon Wasson and his wife traveled to Oaxaca, Mexico and participated in a mushroom ritual. That experience led to a 1957 Life magazine article titled "Seeking the Magic Mushroom." The following year, the Swiss scientist Albert Hofman, who had been the first to synthesize LSD in 1938, identified psilocybin and psilocin as the active compounds in magic mushrooms. In 1960, Timothy Leary and Richard Alpert founded the Harvard Psilocybin Project to study the effects of psilocybin on humans. Harvard University famously fired Leary and Alpert in 1963./nSerious study of magic mushrooms essentially ended when the compounds psilocybin and psylocin were listed as Schedule I drugs in 1971. However, people around the world have used magic mushrooms with the goals of expanding consciousness and achieving spiritual growth ever since it was popularized by the hippies in the the 1960s./nDespite its illegal status, researchers have once again started studying the effects of psilocybin on humans. The results so far have been intriguing. ReasonTV caught up with Roland Griffiths of Johns Hopkins University and Robin Carhart-Harris of Imperial College London at the Psychedelic Science 2013 conference in Oakland, CA to learn what's happening at the cutting edge of psilocybin research./nApproximately 5 minutes.

OUTER HAIR CELLS can contract, and therefore act as motor units that amplify the movement of the basilar membrane in response to a stimulus - some of this added energy is transmitted back through the middle ear, where it can be recorded as an otoacoustic emission think of a swing: if a person sitting on a swing (basilar membrane) pumps his legs (OHC), the amplitude of the swing motion is increased in response to a push (sound stimulus)

Back in June of 2015, a team of scientists led by Mariko Kimura of Kyoto University, became the first to ever see this sort of light through a telescope when a black hole named V404 Cygni, one of the closest to planet Earth, began showing activity after lying dormant for 26 years. Around every six and a half days, Cygni and its partner star (a celestial body a bit smaller than the sun) would circle one another, and when the black hole came to life again, it began feasting on the star. For two weeks, the astronomers were able to see flashes of light — some lasting just minutes, while others continued for several hours — as Cygni worked its magic. “We find that activity in the vicinity of a black hole can be observed in optical light at low luminosity for the first time,” researcher Mariko Kimura told Space.com. “These findings suggest that we can study physical phenomena that occur in the vicinity of the black hole using moderate optical telescopes without high-spec X-ray or gamma-ray telescopes.”

MRI is a noninvasive medical test that physicians use to diagnose and treat medical conditions. This video describes the basic physics of Nuclear Magnetic Resonance and relevant terms such as T1 ; T2 relaxation, pulse sequence, frequency and phase encoding, T1WI and T2WI. Introduces the landmark papers of Drs. Damadian and Lauterbur that made magnetic resonance imaging a reality.

X-ray uses a small amount of radiation that passes through the body to quickly capture a single image of your anatomy to assess injury (fractures or dislocations) or disease (bone degeneration, infections or tumors). Dense objects, such as bone, block the radiation and appear white on the X-ray picture. Radiologists review the pictures and create a report with their findings to aid in diagnosis./nX-ray scan image of the handX-ray is good for:/nAssessing injury (see X-ray scan of the hand to the right) Offering a low-cost, first-look exam/nComputed (Axial) Tomography (CT or CAT scan) is a rapid, 5-20 minute painless exam that combines the power of X-rays with computers to produce 360 degree, cross-sectional views of your body. CT is able to image bone, soft tissue and blood vessels all at the same time. It provides the radiologist with details of bony structures or injuries, diagnosing lung and chest problems, and detecting cancers./nThe technology has a tube design but is slim from front to back, seldom creating anxiety or claustrophobia. A person who is very large may not fit into the opening of the CT scanner or may be over the weight limit for the moving table. While it is a painless process, there is radiation exposure with CT scans. CT is generally not recommended for pregnant women or children unless absolutely necessary. Learn more about the CT experience, see what the technology looks like and read about our dose-reduction efforts/nLung CT scan imageCT is good for:/nImaging bone, soft tissue and blood vessels at the same time Pinpointing issues with bony structures (injuries) Evaluating lung and chest issues (see lung scan image to the right) Detecting cancers Imaging patients with metal (no magnet)/nWhat is an MRI Scan? Magnetic Resonance Imaging (MRI) combines a powerful magnetic field with an advanced computer system and radio waves to produce accurate, detailed pictures of organs, soft tissues, bone and other internal body structures. Differences between normal and abnormal tissue is often clearer on an MRI than CT. There is no radiation exposure with MRI machines./nAn MRI scan can typically last from 30 minutes to an hour since images are taken as cross sections or “slices” of the body part being scanned, as well as other factors such as the type of technology used (high-field versus open or open upright MRI), what the MRI is looking for and if the patient moves. Patients with claustrophobia typically get anxious in a traditional bore scanner due to having to stay still on a hard table for a long period of time. The machine also makes loud knocking sounds. A comprehensive patient screening procedure is followed as due to the magnetic field, special precautions are made or exams may be canceled for patients with cardiac pacemakers, tattoos and metal implants. A person who is very large may not fit into the opening of a traditional tube MRI scanner or may be over the weight limit for the moving table. Read about the MRI experience and hear what an MRI sounds like/nLumbar MRI scan imageMRI is good for:/nImaging organs, soft tissue an internal structures (see spine scan image to the right) Showing tissue difference between normal and abnormal Imaging without radiation
