We all know that exercise is good for our health. But besides lowering the risk of obesity or type II diabetes, exercise has also been shown to benefit our brain. More precisely, exercise modifies parts of the brain and improves memory, attention and improves mood. Regular exercise further lowers the risk to suffer from dementia or depression. But how does exercise benefit our brains?

The new disease could provide insights into how the cell’s recycling system contributes to a healthy brain. Researchers at the National Institutes of Health have discovered a new neurological condition characterized by issues with motor coordination and speech. They identified three children with the condition, two siblings and an unrelated child.

While time may be a worldwide constant, it can be quite tricky. Several individuals have felt like childhood summers were extremely long in comparison to how they experience the same 3 months as adults. Though individuals can argue about time perception and the factors that dilate and compress time, it is possible to look into it experimentally.

Time Perception Is Different For Adults and Children

A team of researchers from Yale and the University of Connecticut (UConn) has developed a nanoparticle-based treatment that targets multiple culprits in glioblastoma, a particularly aggressive and deadly form of brain cancer.

The results are published in Science Advances (“Anti-seed PNAs targeting multiple oncomiRs for brain tumor therapy”).

A new treatment developed by Yale researchers uses bioadhesive nanoparticles that adhere to the site of the tumor and then slowly release the synthesized peptide nucleic acids that they’re carrying. In this image, the nanoparticles (red) are visible within human glioma tumor cells (green with blue nuclei). (Image: Yale Cancer Center)

Dr. Nick Melosh at the BrainMind Summit hosted at Stanford, interviewed by BrainMind member Christian Bailey.

Nick Melosh is a Professor of Materials Science and Engineering, Stanford University. Nick’s research at Stanford focuses on how to design new inorganic structures to seamlessly integrate with biological systems to address problems that are not feasible by other means. This involves both fundamental work such as to deeply understand how lipid membranes interact with inorganic surfaces, electrokinetic phenomena in biologically relevant solutions, and applying this knowledge into new device designs. Examples of this include “nanostraw” drug delivery platforms for direct delivery or extraction of material through the cell wall using a biomimetic gap-junction made using nanoscale semiconductor processing techniques. We also engineer materials and structures for neural interfaces and electronics pertinent to highly parallel data acquisition and recording. For instance, we have created inorganic electrodes that mimic the hydrophobic banding of natural transmembrane proteins, allowing them to ‘fuse’ into the cell wall, providing a tight electrical junction for solid-state patch clamping. In addition to significant efforts at engineering surfaces at the molecular level, we also work on ‘bridge’ projects that span between engineering and biological/clinical needs. My long history with nano-and microfabrication techniques and their interactions with biological constructs provide the skills necessary to fabricate and analyze new bio-electronic systems.”

In a study published in the journal Cell Stem Cell on February 2, researchers show that brain organoids—clumps of lab-grown neurons—can integrate with rat brains and respond to visual stimulation like flashing lights.

Decades of research has shown that we can transplant individual human and rodent neurons into rodent brains, and, more recently, it has been demonstrated that human brain organoids can integrate with developing rodent brains. However, whether these organoid grafts can functionally integrate with the visual system of injured adult brains has yet to be explored.

“We focused on not just transplanting individual cells, but actually transplanting tissue,” says senior author H. Isaac Chen, a physician and Assistant Professor of Neurosurgery at the University of Pennsylvania. “Brain organoids have architecture; they have structure that resembles the brain. We were able to look at individual neurons within this structure to gain a deeper understanding of the integration of transplanted organoids.”
