A new type of microscope that can see through an intact skull
Neuroscience biweekly vol. 21, 30th November — 11th December
TL;DR
- Researchers invented a new type of microscope called reflective matrix microscope, which uses adaptive optics techniques.
- Restoration of vision in blind people through a brain implant is on the verge of becoming reality. Recent discoveries at the Netherlands Institute for Neuroscience (NIN) show that newly developed high-resolution implants in the visual cortex make it possible to recognize artificially induced shapes and percepts.
- An experimental drug called ISRIB has been shown to reverse age-related declines in memory and mental flexibility in mice. In the new study, published in eLife , researchers showed rapid restoration of youthful cognitive abilities in aged mice, accompanied by a rejuvenation of brain and immune cells that could help explain improvements in brain function.
- The tree of life describes the evolution of life and seeks to define the relationships between species. Likewise, the tree of cell types aims to organize cells in the brain into groups and describe their relationships to each other.
- A new study suggests that the language a bilingual person speaks can affect their physical sensations, depending on the cultural association tied to each vernacular.
- Researchers use connectomic mapping in the developing cortex to uncover the developmental wiring rules for inhibitory neurons.
- New research has confirmed in laboratory testing that a population of nerve cells near the base of the brain — the RFRP neurons — become active in stressful situations and then suppress the reproductive system.
- Have you recently wondered how social-distancing and self-isolation may be affecting your brain? An international research team led by Erin Schuman from the Max Planck Institute for Brain Research discovered a brain molecule that functions as a “thermometer” for the presence of others in an animal’s environment. Zebrafish “feel” the presence of others via mechanosensation and water movements — which turns the brain hormone on.
- Reactive oxygen molecules, also known as “free radicals”, are generally considered harmful. However as it now turns out, they control cellular processes, which are important for the brain’s ability to adapt — at least in mice.
- In a new paper, researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) report brain chemistry that may contribute to why drinkers have difficulty paying attention while under the influence.
