The study, conducted in the USA and first published in the journal Stroke is titled “Long-Term Exposure to Fine Particulate Matter, Residential Proximity to Major Roads and Measures of Brain Structure“. Examining the brains of more than 900 people over 60 years old, it revealed that long-term exposure to fine dust causes both ...
We wrote in a recent blog, The threat from particulates: It gets worse about an American academic study: “Long-Term Exposure to Fine Particulate Matter, Residential Proximity to Major Roads and Measures of Brain Structure.” The report clearly shows the risks that people living over extended periods near busy main roads face from fine dust that causes ...
The human brain has long been regarded as one of the most enigmatic subjects in both medicine and science, captivating interest since ancient times. ...
The unique molecular structure enables it to have good tissue penetration, shorter half-life and higher renal clearance rate, and can penetrate the blood-brain barrier. ...
In the field of scientific research, understanding and studying emotion-related behaviors in animals plays a crucial role in advancing the knowledge of the human brain and mental health. Animal models can help researchers better comprehend animal behaviors, and rodent models in particular have become important objects for understanding the mechanisms of emotional behaviors and ...

Introduction Neurologic complications are frequently reported in COVID-19, but our understanding of their pathophysiologic causes and neuroanatomical correlates is limited. While several structural brain imaging findings have been reported in COVID-19, including non-spherical signal abnormalities on Susceptibility-Weighted Imaging (SWI), conventional perfusion ...
Carrie Fisher was an American actress most well known for her role as Princess Leia in the Star Wars films (1977-1983 and 2015-2019). She was the daughter of singer Eddie Fisher and actress Debbie Reynolds. Carrie Fisher wrote the semi-autobiographical book Postcards from the Edge and the autobiography Wishful Drinking, which she turned into a one-woman stage show. She was open throughout her ...
Bipolar disorder is thought to be caused by a combination of genetics, exposure to stress, and differences in brain structure. It is typically treated with mood stabilizers, antipsychotics, and antidepressants. ...
Pharmacotherapy, talk therapy, and support group-based therapy are feasible, but relapse is common, mainly due to limited knowledge of brain circuit dysfunction behind AUD. Scientists know that promoting the relapse of alcohol withdrawal symptoms, including a rise in anxiety, is caused at least in part by the release of stress molecules in the brain, such as ...
In particular, a clearer understanding of the changes in brain structures that could predict treatment success. Previous studies have reliably demonstrated the involvement of the insula as well as the thalamus and hippocampus. However, there is still room to further ascertain the relationship between brain region activation/deactivation by tVNS ...
MRI Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a very large magnet, radio waves, and a computer to produce detailed, cross-sectional, and three-dimensional images of organs and structures within the body. An MRI scan is a valuable diagnostic tool that can show injuries or other anomalies that cannot be seen in a CT scan or X-ray. ...
Scientists at Cornell University developed a technique for imaging the brain of an adult zebrafish, with the goal of better understanding human brain disorders. ...
Why does exercise feel so good for the brain? How can simple walking be so beneficial for the brain and just as effective as medication for treating depressive symptoms? ...
Stereotaxic injections Stereotaxic injections have been widely used in neuroscience for in vivo delivery of agents to targeted brain structures of experimental animals. Syringe pumps are a part of a complex system encompassing a stereotaxic frame and a stereotaxic atlas, assuring an accurate placement of biochemical agents. ...
Special nerve cells leading to the brain have hair-like structures floating in the inner ear fluid. Movement of the eardrum, middle ear and inner ear fluid cause these “hairs” to sway back and forth. When they move, nerve impulses are sent to the brain where they are interpreted as sound soft or loud, pleasant or unpleasant, high ...
Such interference can affect how the brain develops structurally and functionally — effects that lead to lasting adverse outcomes. “The brain is so extremely sensitive to external stimulation,” says Grandjean. ...

Special nerve cells leading to the brain have hair-like structures floating in the inner ear fluid. Movement of the eardrum, middle ear and inner ear fluid cause these “hairs” to sway back and forth. When they move, nerve impulses are sent to the brain where they are interpreted as sound soft or loud, pleasant or unpleasant, high pitched or low ...
