Back in July, I shot one of the coolest, weirdest, most fascinating stories I’ve worked on to date. It was for the French quarterly magazine We Demain, and it covered the DIY brain stimulation movement. This type of brain stimulation sends very small electric currents through the brain for extended amounts of time (15-25 minutes) and is believed to treat a whole host of ailments, including chronic pain, depression, fibromyalgia, and poor cognitive function. It also can improve memory, advocates say. Yes, this is a real thing.
