Designing Implants that Don’t Scar the Brain
Can brain implants restore sight? Researchers have mapped how the brain reacts to neural probes, finding that flexible polyimide is the key to long-term biocompatibility.
Minibrains Reveal Personalized Paths for Rett Syndrome
Neuroscientists used 3D “minibrains” to discover that different Rett syndrome mutations cause distinct brain abnormalities. The study reveals that personalized treatments, tailored to specific genetic mutations, are necessary for the disorder.
Right-to-Left Brain Circuit Essential for Navigation
Researchers have discovered a neural circuit connecting the right and left hippocampus that is vital for spatial memory. The study also links the disruption of this “bridge” to schizophrenia-related cognitive deficits.
The Loneliness Paradox: Memory Deficits Without Accelerated Decline
Does loneliness cause dementia? A new study shows that while lonely seniors have poorer memory at the start, their cognitive decline follows the same trajectory as non-lonely peers.
Inhibitory Neurons Drive Rhythmic Movement
How do fruit flies move? A new study reveals that inhibitory neurons, traditionally seen as “brakes,” coordinate the rhythmic grooming motions of Drosophila by toggling muscle inhibition.
Glowing Nanoparticles Injected In The Bloodstream Stimulate The Brain Without Surgery
No brain surgery or implanted hardware necessary. Just an injection and a directed pulse of ultrasound that makes the particles glow wherever the beam is pointed, whether that’s the brain, the spinal cord, or anywhere else the blood flows.
