All Too Human
New research suggests that our brains are like modern washing machines – evolved to have the latest sophisticated programming, but more vulnerable to breakdown and prone to develop costly disorders. Researchers compared the efficiency of the neural code in non-human and human primates, and found that as the neural code gets more efficient, the robustness that prevents errors is reduced.

Why Being Rocked to Sleep is Best for the Brain
Anyone who has ever put a baby to sleep by gently cradling it or has ever taken a nap in a hammock knows that rocking promotes sleep. But why? A new study shows that slow and repeated movement throughout the night modulates brain wave activity. Consequently, not only does balancing induce deeper sleep, but it also helps to strengthen memory, which is consolidated during certain sleep phases.

Graphene Sensor Can Hear Your Brain Whisper
A newly developed graphene-based implant can record electrical activity in the brain at extremely low frequencies and over large areas, unlocking the wealth of information found below 0.1 Hz. A new study, just published in Nature Materials, describes how this ground-breaking technology will enhance our understanding of the brain and pave the way for the next generation of brain-computer interfaces.

Study Implicates Gum Disease Bacteria in Alzheimer's Pathology
Porphyromonas gingivalis, the central bacterium involved in chronic periodontitis, was found in the brains of Alzheimer’s disease patients. In mice, infection by the bacterium resulted in increased production of amyloid plaque components, and toxic bacterial proteases were observed in the brains of these mice. Small molecules aimed at blocking these proteases rescued some of these pathological features.

High Blood Pressure Linked in Brain Shrinkage Even in Young Adults
For people in their 20s and 30s, having blood pressure above normal but below the level considered to be high blood pressure, may be linked to loss of brain volume, according to a new study. People with blood pressure above normal were more likely to have a loss of volume in the gray matter in certain areas of the brain than people with normal blood pressure.
