Stimuli Fading Away en Route to Consciousness

The researchers are basing their study on a well-known phenomenon: When presented with two images in rapid succession, humans can only consciously perceive the second one if there is sufficient time between the two presentations. In this study the participants saw a series of pictures on a computer screen, where

Nutrition has Benefits for Brain Network Organization

The study of 99 healthy older adults, recruited through Carle Foundation Hospital in Urbana, compared patterns of fatty acid nutrients found in blood samples, functional MRI data that measured the efficiency of brain networks, and results of a general intelligence test. The study was published in the journal NeuroImage. "Our goal is

Human Skin Cells Transformed Directly Into Motor Neurons

In new research, scientists at Washington University School of Medicine in St. Louis have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly

Mind Wandering is Common During Driving

Are you always attentive when driving? How about on the monotonous commute home after a long day's work? It can be difficult to keep our attention sharp while driving, especially on routes that we drive daily, or when we are tired after work. However, driver inattention is a major factor

Zika Virus Kills Brain Cancer Stem Cells

The findings suggest that the lethal power of the virus -- known for infecting and killing cells in the brains of fetuses, causing babies to be born with tiny, misshapen heads -- could be directed at malignant cells in the brain. Doing so potentially could improve people's chances against a

New Source for Brain’s Development Discovered

The research, which appears in the journal Science, discovered that glia, a collection of non-neuronal cells that had long been regarded as passive support cells, in fact are vital to nerve-cell development in the brain. "The results lead us to revise the often neuro-centric view of brain development to now appreciate the

Fragile X Syndrome Early Detection Important

This picture of the basic nature of Fragile X has been reinforced by a series of studies reported in a paper titled "Fragile X Mental Retardation Protein Requirements in Activity Dependent Critical Period Neural Circuit Refinement" published Aug. 7 in the journal Current Biology. The research was conducted by a team of

Brain Cells Found to Control Aging

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult
