Vision researchers have disproved a long-standing theory of how the human vision system processes images, using computational models and human experiments. The findings could have implications for the understanding of human vision and diagnosis of vision anomalies.
Read moreResearchers have identified a potential approach to stop the growth of the most common type of brain tumor in children.
Read moreNew cellular and molecular processes underlying communication between gut microbes and brain cells have been described for the first time.
Read moreNeuroscientists say they have identified how people can have a 'crash in visual processing' — a bottleneck of feed-forward and feedback signals that can cause us not to be consciously aware of stimuli that our brain recognized.
Read moreMedical researchers have demonstrated how estrogen — a natural hormone produced in the body — can be polymerized into a slow-releasing biomaterial and applied to nervous system cells to protect those cells and even promote regeneration.
Read morePatients who survive a cerebral hemorrhage may suffer delayed severe brain damage caused by free hemoglobin, which comes from red blood cells and damages neurons. Researchers have now discovered a protective protein in the body called haptoglobin, which prevents this effect.
Read moreNeuroscientists say they have developed and tested an agent that reduces the buildup of toxic proteins in animal models of both Parkinson's and Alzheimer's diseases, and improves cognitive and motor behavior.
Read moreHuman-made toxic chemicals that linger indefinitely in the environment disrupt the performance of critical helper cells in the mouse brain, leading to impaired function over long-term exposures.
Read moreOur brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today's discovery helps to solve a long-standing scientific question as to how the brain's listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain.
Read moreScience tells us that a lot of good things happen in our brains while we sleep — learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia — which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage — are also primarily active while we sleep.
