IEEE Spectrum magazine published an excellent deep and engaging look at how electricity is now being used to cure, or at least relieve, severe cases of depression. The techniques involve electromagnetically tweaking specific parts of the brain via implanted electrodes, current, or magnetic fields. (Previous posts on the subject here, here, and here. I also wrote about it in Popular Science in 2004.) The devices range from a "pacemaker" for your brain to a transcranial magnetic stimulator (seen here) that is used for just minutes each day but can alter your brain in the long term. From the article:
One problem with (neuropharmaceuticals) is that drugs work everywhere in the brain that their chemical target exists, regardless of whether those parts have anything to do with depression or any other disease, and that leads to side effects. Prozac, for example, has been known to reduce sex drive and can cause insomnia. Another problem is that brain chemistry varies from person to person, so no single drug will work in everyone.
The shared goal behind the new electromagnetic therapies, on the other hand, is to use electricity itself to restore the signaling, ideally, only in those parts of the brain affected by disease. Decades ago, neuroscientists demonstrated that electrically stimulating a neuron alters, in the long term, the strength of its connections to other neurons–making an electrical signal from one neuron more likely or less likely to jump to the next neuron. Though little is known in detail about how the new therapies work, it's likely that, to varying degrees, they depend on that phenomenon.
I asked Amy Parness, the co-founder of Sparkle Labs, maker of fantastic educational electronics kits, to write a Medium post about gender and the business of being a maker business person. Her terrific essay calls out the problems with “pink girly engineering kits.” From Medium:
Zero UI is the new term for “invisible interfaces”—what happens in the future when all the clicking and tapping and typing is history: “If you look at the history of computing, starting with the jacquard loom in 1801, humans have always had to interact with machines in a really abstract, complex way.” [Fast Company]
Lean Project Management, as the name suggests, is a popular method for wasting less time and effort over the duration of a project. By focusing on prioritizing tasks, Project Managers are able to boost productivity, meet goals, and, inevitably, impress the execs. This exam prep course is led by the accredited Management and Strategy Institute, […]
