Multiple system atrophy (MSA) is a progressive neurodegenerative disorder characterized by a combination of symptoms that affect both the autonomic nervous system (the part of the nervous system that controls involuntary action such as blood pressure or digestion) and movement.aTscan can assess the dopamine transporter in a part of the brain called the striatum and can help physicians determine if the condition is caused by a dopamine system disorder; however this test cannot differentiate between MSA and Parkinsonâs disease.
The maximum length you can run an HDMI cable depends mostly on the power output of the device, so it varies. It typically tops out at 50 feet, though, and anything beyond that requires some type of extender.
The cable quality factors that really matter in HDMI cable are, primarily, impedance control on the TMDS pairs (which do the heavy lifting in the HDMI cable), and skew, which is a measure of the difference in electrical length of the conductors and pairs (by electrical length, we mean the length of the wire, as measured by the time it takes a pulse to travel down the line; this may vary from physical length for a number of reasons, most but not all of which are related to impedance control).
