Using direct human brain recordings, a research team from Drexel University, the University of Pennsylvania, UCLA and Thomas Jefferson University has identified a new type of cell in the brain that helps people to keep track of their relative location while navigating an unfamiliar environment. The "grid cell," which derives its name from the triangular grid pattern in which the cell activates during navigation, is distinct among brain cells because its activation represents multiple...

Lighting The Way To Understand The Brain

Norwegian University of Science and Technology Scientists can see which cells communicate with each other in the brain, by flipping a neural light switch There are cells in your brain that recognize very specific places, and have that as one of their main jobs. These cells, called place cells, are found in an area behind your temple called the hippocampus. While these cells must be sent information from nearby cells to do their job, so far no one has been able to determine exactly what...

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...

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...
