Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It's quite disgusting that this information is not available from every stroke association and doctors group.

One step ahead – What happens in the brain before a bungee jump?

I want to know what the chances are of tearing plaque loose in your brain as you do this.

Surjo R. Soekadar, psychiatrist and neuroscientist at the University of Tübingen, and his doctoral candidate Marius Nann have for the very first time succeeded in measuring the readiness potential, outside a laboratory and under extreme conditions, namely prior to a 192-meter bungee jump.
The readiness potential is a characteristic electrical voltage shift in the brain that indicates an upcoming willful act, and that appears even before a person becomes aware of his/her own conscious decision to act. The results of the study will be published in an international journal later this spring but are now available online: https://www.biorxiv.org/content/early/2018/01/27/255083 (DOI: https://doi.org/10.1101/255083)
The readiness potential was first described in 1964 by Hans-Helmut Kornhuber and Lüder Deecke, who measured the brain waves of a test person over hundreds of finger movements and under strict laboratory conditions. Despite numerous studies, the readiness potential has never been measured in a real-life situation: Since the voltage shift is in the range of only a few millionths of a volt, only measurements under laboratory conditions were considered possible.
To advance the development of brain-machine interfaces, the researchers from Tübingen wanted to find out whether the readiness potential can be assessed in everyday environments. In addition, they were interested in whether the willpower necessary for initiating an act would influence the characteristics of the brain potential. For the study, two semi-professional cliff divers agreed to have their brain waves recorded before jumping from the second tallest bungee jumping platform in Europe, the 192-meter Europa Bridge near Innsbruck in Austria.
After only a few jumps, the researchers were able to measure the readiness potential beyond any doubt. "Once again, the current experiment shows that the boundaries of the possible are shifting and that neurotechnology might soon be part of our everyday life," Soekadar says. “The small number of jumps necessary for the experiment shows that the readiness potential prior to a bungee jump is very well expressed”, Nann explains.
