The new soft implantable probe can monitor fluctuations in chemicals in the brain

The new string-like implant can monitor fluctuations in chemicals in the brain, as a fitness tracker for the brain. An imbalance in brain chemistry is the basis of many neurological diseases. These same brain chemicals also play a role in gut health. So Stanford researchers have invented the “NeuroString” – a soft implantable probe that …

Brain cell activity plays a key role in the outcomes of CNS disorders

Cedars-Sinai researchers have comprehensively mapped the molecular activity in the brain and spinal cord that is responsible for regulating the body’s response to central nervous system (CNS) disorders, such as Alzheimer’s disease, Huntington’s disease, and spinal cord injuries. The research focused on cellular changes in astrocytes, a type of specialized support cell in the brain …

Surprising results trigger the release of norepinephrine in the brain, the MIT study found

When your brain needs you to pay attention to something important, one way it can do this is to send a burst of norepinephrine, according to a new MIT study. This neuromodulator, produced by a structure deep in the brain called the locus coeruleus, can have extensive effects throughout the brain. In a mouse study, …

Gene therapy for retinal degenerative diseases has no safety concerns, but cannot improve vision loss

A Phase 1 gene therapy clinical study in 28 patients with Leber hereditary optic neuropathy (LHON) degenerative retinal disease did not identify any significant safety concerns; however, treatment failed to improve or slow vision loss, even at the highest dose. LHON affects the optic nerve, which transmits visual signals from the retina sensing light to …
