Cornell scientists have developed a new technique for imaging a zebrafish’s brain at all stages of its development, which could have implications for the study of human brain disorders, including autism.
In an effort to mitigate the spread of COVID-19 and to optimize allocation of healthcare resources, researchers are improving ways to treat patients with acute large vessel occlusion strokes in a safe manner that also better protects health care workers.
Researchers at Aalto University and Turku PET Centre have developed a new method for simultaneous imaging brain activity from two people, allowing them to study social interaction.
Biological robots draw inspiration from natural systems to mimic the motions of organisms, such as swimming or jumping. Improvements to biobots to better replicate complex motor behaviors can lead to exciting biorobotic engineering applications to help solve real world challenges. However, this requires the creation of biohybrid, which is a challenge. Researchers combined an intact rat spinal cord with a tissue-engineered, 3D muscle system. They describe the novel biohybrid system in the journal APL Bioengineering.
Researchers at UC San Diego School of Medicine and three German universities describe an underlying biological basis for myalgic encephalomyelitis/chronic fatigue syndrome, illustrating how efforts by the body to boost immune system protections can come at physiological cost elsewhere.
Antibiotic treatment — which depletes gut microbes — drastically changes the parts of a rat’s brain that are activated during opioid addiction and withdrawal.
Doctors who treat stroke and heart attack patients are trying to find out why they have been seeing fewer patients with these life-threatening emergencies during the COVID-19 pandemic. Is COVID-19 somehow preventing emergencies from happening? Or, are people ignoring symptoms and staying home instead of seeking the medical care they need?
Functional MRI (fMRI), a type of scan that measures brain activity, has enabled study of the impact of alcohol on brain function. This type of imaging allows brain activity to be assessed while participants are at rest, performing a simple task like tapping a finger, or doing a complex cognitive task like a memory task or decision-making. It works by detecting the change in blood flow that occurs when brain cells (or neurons) in different parts of the brain are activated. Blood flow provides the energy and oxygen needed for brain cells to activate, and it is this exchange of oxygen that is measured using fMRI and is reflected by brain blood flow. Complicated physics are involved in determining the profile of blood flow when a part of the brain is activated, and studies have shown that the time course of these changes – known as the hemodynamic response function (HRF) – is affected by acute alcohol consumption. However, the effects of heavy chronic (long-term) alcohol consumption on HRF
Researchers have created 3D tissue structures that recapitulate many aspects of specific human brain regions.
In a new animal study examining Alzheimer’s disease, researchers found that disease progression could be slowed by decreasing neuroinflammation in the brain before memory problems and cognitive impairment were apparent.
Many hospitals across the country have noticed an increase of people ignoring life-threatening symptoms. They are choosing to stay home, instead of seeking care at an emergency department. When they do arrive at the hospital, the patient has lost critical time to receive life-saving treatments.
Led by Biomedical Engineering Prof Dion Khodagholy, researchers have designed biocompatible ion-driven soft transistors that can perform real-time neurologically relevant computation and a mixed-conducting particulate composite that allows creation of electronic components out of a single material. These have promise for bioelectronic devices that are fast, sensitive, biocompatible, soft, and flexible, with long-term stability in physiological environments such as the human body. In particular, they could facilitate diagnosis and monitoring of neurological disease.
Announcement of four new editorials on the impact of the COVID-19 pandemic on the practice of neurosurgery.
It’s no secret that a healthy diet may benefit the brain. However, it may not only be what foods you eat, but what foods you eat together that may be associated with your risk of dementia, according to a new study published in the April 22, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A new study explains how cocaine modifies functions in the brain revealing a potential target for therapies aimed at treating cocaine addiction. The study was published this week in Cell Reports.
A postmortem exam of the brain remains the gold standard for diagnosing chronic traumatic encephalopathy, or CTE, the neurodegenerative brain disease believed to arise from repeated hits to the head. Yet a small but by no means trivial number of former professional football players say they have received a diagnosis of CTE, according to a new study. Even though the results are based on player self-reports rather than on documented clinical diagnoses, the researchers say their findings are alarming for a number of reasons.
A UC Davis Health study found more evidence for the efficacy of behavioral intervention in treating language problems in youth with fragile X syndrome (FXS), but none for lovastatin as a treatment for FXS.
University of Illinois at Chicago researchers report that in depressed individuals there are increased amounts of an unmodified structural protein, called tubulin, in lipid rafts — fatty sections of a cell membrane — compared with non-depressed individuals.
