Jedidiah Becker for redOrbit.com — Your Universe Online In 2005, Norwegian researchers discovered a previously unknown type of neuron by placing electrodes deep within the cerebral cortex of rats. Dubbed “grid cells,” these specialized neurons were so named because they fire in distinct clusters, each of which constitutes the vertex of a grid-like pattern of equilateral triangles. This recurring triangular, lattice-like firing pattern is what distinguishes grid cells from other...

A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University. The team, led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State, has found that a mutation in a single gene can entirely shut down the process by which axons -- the parts of the nerve cell that are responsible for sending signals to other cells -- regrow themselves after being cut or damaged. "We are...

Monkeys Deconstruct The World Through Triangular Grids

Brett Smith for redOrbit.com - Your Universe Online Researchers at Emory University have shown that some primates visually deconstruct the world through triangular grids. According to their report in the journal Nature, the scientists have identified grid cells in the brains of rhesus monkeys that fire in triangular patterns as their eyes scan a scene. Uncovering this brain activity in primates could have larger ramifications as the grid cells are connected to how we view and recall...

Researchers Find Easier Way To Perform Macular Degeneration Eye Test

Lawrence LeBlond for redOrbit.com - Your Universe Online Age-related Macular Degeneration (AMD) is a condition that generally occurs in people over the age of 50, but also occurs in higher numbers of people who smoke, who are white, and people who have a family history of the often debilitating condition. And for those who had gone through AMD testing, they had generally had to sit in a darkened room for 20 minutes before testing had begun. But now, researchers from Australia´s...

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment. B cells, said Robert Lisak, M.D., professor of neurology at Wayne State and lead author of the study, are a subset of lymphocytes (a type of circulating white blood cell) that...

Korean scientists have used tiny stars, squares and triangles as a toolkit to create live neural circuits in a dish. They hope the shapes can be used to create a reproducible neural circuit model that could be used for learning and memory studies as well as drug screening applications; the shapes could also be integrated into the latest neural tissue scaffolds to aid the regeneration of neurons at injured sites in the body, such as the spinal cord. Published today, 20 July, in IOP...

Research shows mice brains are 'very wired up' at birth, and suggests experience selects which connections to keep Ask the average person the street how the brain develops, and they'll likely tell you that the brain's wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, and new branches are built as they learn and grow. A new study conducted in a Harvard lab, however, suggests that just the opposite is true. As...

A molecule responsible for the proper formation and function of neurons finds its way to the right place not because it is actively recruited, but because it can't go anywhere else. Researchers at Baylor College of Medicine have identified a distal axonal cytoskeleton that functions as a boundary to ensure a key scaffolding protein, called ankyrinG, stays at the start of the axon near the cell body where it performs its functions of clustering sodium and potassium ion channels and...
