The best in neuroscience this week from around the web:
Maclean’s – Slipping Away [SIMPLE SCIENCE / LONG READ]
LOSING IT: What’s it like to live with Alzheimer’s Disease? This article explores the effect the disease has on a 38-year-old Canadian man with early-onset, familial Alzheimer’s, as well as the heartbreaking moments of realisation he and his wife have as the disease progresses.
Singularity Hub – This Robotic Hand Wired to a Brain Implant Restored a Paralyzed Man’s Sense of Touch [SIMPLE SCIENCE / SHORT READ]
FEELS GOOD: A few years ago a quadriplegic woman used only her thoughts to control a robotic arm, allowing her to drink a coffee; very impressive, very cool, but also a bit clunky. Now, researchers have incorporated a sense of touch into a robotic arm, offering the patient greater control and making him feel as though the arm is really his and not just a mechanical appendage.
MIT Technology Review – The False Science of Cryonics [MEDIUM SCIENCE / MEDIUM READ]
DISNEY ON ICE: Urban legend has it that Walt Disney chose to be cryogenically frozen after his death. The myth has endured for as long as the belief in cryonics itself has. People pay up to $80,000 to freeze their brains, but here’s why you should save your money.
Nature News – Worm’s Brain Cells Switched On With Ultrasound [COMPLEX SCIENCE / MEDIUM READ]
SOUNDS PROMISING: Optogenetics is a 10-year-old tool that uses light to turn neurons on and off. As revolutionary as it has been for neuroscience, one problem is that light doesn’t pass through our thick skulls, so human optogenetic applications remain a long way off. Enter ‘sonogenetics’, which uses penetrating ultrasound waves to control individual neurons (so far just in worms).
The Guardian – What happens in your brain when you make a memory? [SIMPLE SCIENCE / MEDIUM READ]
COMMIT TO MEMORY: Actually how short is short-term memory? Where in the brain are memories stored? What happens when you recall something you didn’t realise you’d forgotten? This explainer has you covered.
