Brain (10) 썸네일형 리스트형 optofluidics for detecting brain injury A method for detecting traumatic brain injury at the point of care has been developed by scientists at the University of Birmingham. Using chemical biomarkers released by the brain immediately after a head injury occurs, researchers are able to pinpoint when patients need urgent medical attention. This saves time in delivering vital treatment and avoids patients undergoing unnecessary tests wher.. relationship between BBB & neural activity stm.sciencemag.org/content/12/564/eabe8119 it is commonly known that vascular function can affect neural activity; indeed, decreased brain perfusion impedes neural function. Conversely, neural activity can influence vascular function; for instance, neural activity induces blood flow changes, yielding the contrast mechanism of fMRI. A recent study by Pulido and colleagues has taken this story fur.. nano device mimicking neuron - nature *** To build the fundamental building block of the brain or a neuron, the researchers assembled a synthetic nanoscale device consisting of layers of different inorganic materials, each with a unique function. However, they said the real magic happens in the thin layer made of the compound niobium dioxide When a small voltage is applied to this region, its temperature begins to increase. But when the.. Astrocyte - BBB supporter Now, in a study with potential impacts on a variety of neurological diseases, Virginia Tech researchers have provided the first experimental evidence from a living organism to show that an abundant, star-shaped brain cell known as an astrocyte is essential for blood-brain barrier health. Furthermore, the finding gives scientists a path to understand diseases where frequent blood-brain barrier da.. 알콜중독이 강력한 이유 The researchers have here observed that alcohol may increase its addictive capacity by changing the geometry of the brain, specifically the gray matter, as shown by this translational study carried out in rats and humans, published today in the journal Science Advances According to their observations, the cells of the immune system that reside in the brain, called microglia, are responsible for .. 두려움과 기억의 관계 Most people can remember where they were on 9/11, or what the weather was like on the day their first child was born. Memories about world events on Sept 10, or lunch last Tuesday, have long been erased. Why are memories attached to emotions so strong? "It makes sense we don't remember everything,""We have limited brain power. We only need to remember what's important for our future wellbeing." .. 조헌병의 EEG pattern People with schizophrenia and their healthy siblings share patterns of brain activity that are different from those seen in individuals with no family history of the disorder, scientists from EPFL have found. Because the siblings do not show schizophrenia symptoms, this brain 'signature' could serve as a marker for the early diagnosis of the disorder. The findings, published in Nature Communicat.. microglia의 새로운 역할 발견 (promoting synapse plasticity) To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons' long, branching tentacles dock neurons together so they can talk. These ports of cellular chatter—called synapses, and found in the trillions throughout the brain—allow us to represent new knowledge. But scientists are still learning just how these connections form in respo.. 이전 1 2 다음
