New microfluidic system using artificial membrane keep brain tissue viable for a longer duration

Researchers at the RIKEN Center for Biosystems Dynamics Research in Japan have developed a new system for keeping tissue viable for long-term study once transferred from an animal to a culture medium. The new system uses a microfluidic device made of polydimethylsiloxane (PDMS) with a porous membrane that can keep tissue from both drying out …

Researchers find possible link between autism and nuclear receptor protein LXRβ

Research by University of Houston scientists discovered a possible link between nuclear receptor protein LXRβ (Liver X receptor Beta) and autism spectrum disorder. They found that nuclear receptor LXRβ deletion causes poor development of dentate gyrus, a part of brain’s hippocampus. The dentate gyrus, or DG, is responsible for emotion and memory and is known …

A new algorithm to solve memory problems in large-scale human brain simulations

 Researchers have come closer towards advancing technology to create computer simulations of the brain networks using exascale-class supercomputers. Their findings are published in journal  Frontiers in Neuroinformatics. Credit: Forschungszentrum Jülich The human brain is a complex network composed of approximately 100 billion neurons. With current computing power, it is impossible to simulate 100 percent working brain. …

Protein Wnt5a is important in sustaining adult neuron structure in mice hippocampus

Humans and other vertebrates depend on a portion of the brain called the hippocampus for learning, memory and their sense of location. Nerve cell structures in the adult hippocampus are sustained by factors whose identities have remained largely mysterious so far. Now, research led by a Johns Hopkins University biologist Dr. Kuruvilla sheds light on …

Using focused magnetic stimulation of brain to improve precision memory

Northwestern Medicine scientists showed for the first time that non-invasive brain stimulation can be used like a scalpel, rather than like a hammer, to cause a specific improvement in precise memory. This is an individual receiving noninvasive brain stimulation (‘high-frequency, repetitive, transcranial electromagnetic stimulation’). Credit: Northwestern University  Precise memory, rather than general memory, is critical …

Increased brain connectivity seen in endurance runners.

University of Arizona researchers discovered that MRI scans of endurance runners’ brains have greater functional connectivity than the brains of more sedentary individuals. Researchers compared brain scans of young adult cross country runners to young adults who don’t engage in regular physical activity. The runners, overall, showed greater functional connectivity or connections between distinct brain …

Magnetoencephalography and computational analysis to accurately diagnose concussions

Simon Fraser University researchers have found that high-resolution brain scans, coupled with computational analysis, could play a critical role in helping to detect concussions that conventional scans might miss. In a study published in PLOS Computational Biology, Vasily Vakorin and Sam Doesburg show how magnetoencephalography (MEG), which maps interactions between regions of the brain, could …
