A growing body of evidence, dating back to the late 1960s, suggests that we can lessen the emotional blow of negative memories (and even get rid of them altogether) months and years after those memories originally formed. The key is that memories seem to be vulnerable to manipulation and erasure as you're recalling them, not just at the time of creation. The newest research — and some of the most convincing to date — used electroconvulsive therapy to effectively remove the details of traumatizing stories from the minds of healthy volunteers. Virginia Hughes has a story about the newest study at her blog:
Schiller’s experiments have also bolstered the reconsolidation hypothesis. She has shown, for example, that if people recall a fearful memory and then go through ‘extinction learning’ — meaning that they’re shown the fearful stimulus over and over again without any pain — they can erase the emotional sting of the memory. Other groups have shown something similar by giving people propranolol, a beta-blocker, immediately after recalling a memory.
The new study adds ECT to the list. There are still a lot of questions. For example, it’s not clear how ECT is disrupting reconsolidation. Or if it’s doing it at all: The effect could be partly or wholly due to anesthesia, though the researchers say this is unlikely. Most importantly, no one knows whether the procedure would work with old, real memories, as opposed to those artificially created in the lab.
Teams of researchers are developing sesame seed-size neuro-implants that detect brain activity that signals depression and then deliver targeted electrical zaps to elevate your mood. It’s very early days in the science and technology but recent studies suggest that we’re on the path. Links to scientific papers below. Fortunately, the goal is to develop tools […]
In the 1960s, when Scientific American copy editor Michael J. Battaglia was 15, he had a chemical romance with the periodic table. In fact, Battaglia was so fascinated by the basic substances of our universe that he tried to collect ’em all (at least the 104 elements that science knew about at the time.) From […]
Aren’t they beautiful? Here’s how ‘ghost apples’ formed on this apple tree in West Michigan.
What do Facebook, Twitter, YouTube and Google all have in common? Somewhere in their framework, they all use MySQL, that most versatile (and free!) of database management systems. And they’re not alone. If your company or the one you’d like to work for wrangles data (and who doesn’t?), they’re going to need someone with a […]
There’s a reason you’re hearing about the gig economy in every other business story these days. More than ever, people are finding income from more than one source. And if you find the right one, a side hustle can do more than just pad your pockets – it can allow you to finally get paid […]
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
