A study published in the British Journal of Psychiatry found that pathological liars have a surplus of white matter and a deficit of gray matter in their brains. This suggests they have more tools to lie but fewer moral restraints than normal people.
Researchers discovered that hyaluronic acid inhibits oligodendrocyte progenitor maturation, leading to brain damage. The findings offer clues on reversing some forms of brain damage and improving lives of thousands of infants.
A new UCI study finds that men and women use different brain areas to achieve similar IQ results, with women having more white matter and men having more gray matter related to intellectual skill. The study suggests that human evolution has created two different types of brains designed for equally intelligent behavior.
Researchers at Stanford and Packard find that premature boys' brains are more severely affected than girls in areas responsible for reading, language, emotion, and behavior. The study reveals a significant disparity between preterm males and females, with preterm boys struggling more with speech and language.
A study analyzing 36 white matter plaques in 20 MS patients showed diffusion tensor MRI to be 45% more sensitive than T2-weighted imaging in measuring diseased white matter. This could lead to earlier detection of abnormalities and improved assessment of therapy effectiveness.
Researchers found that a blood pressure-lowering regimen in stroke patients can stop or delay further ischemic brain damage. The study showed that patients who received the medication had significantly fewer new white matter lesions compared to those who took placebo.
Elderly individuals with white matter abnormalities and infarcts exhibited accelerated cognitive decline compared to those with fewer abnormalities. A serious increase in white matter lesions was associated with a higher risk of developing dementia and depression over a period of five years.
Researchers found no signs of impending brain injury from fetal heart rate monitoring, highlighting the need for alternative diagnostic methods. White matter brain injury is a common cause of cerebral palsy, but current monitoring systems may not be effective in detecting it.
Researchers identified specific areas of white matter enlargement linked to myelination delays in autistic and DLD patients. Enlargements were most pronounced in the prefrontal area and the outer layer of white matter was significantly larger than in normal controls.
Research finds that neonatal white matter injury is associated with culture-positive infections and rare instances of metabolic acidosis. The study refutes the idea that delivery complications cause these injuries.
A new study found that moderate alcohol intake may promote brain atrophy, which can lead to lower cognition and reduced extremity function. The research, published by the American Heart Association, used magnetic resonance imaging (MRI) to assess brain abnormalities in middle-aged adults.
Researchers used DTI to study adolescents with early-onset schizophrenia and found distinct differences in white brain matter of the frontal lobe. This disruption can lead to developmental abnormalities and abnormal behaviors.
A new model suggests that the Big Bang could have been an explosion within a black hole, with the universe expanding into an infinite space. The theory, developed by UC Davis and University of Michigan mathematicians, satisfies Einstein's equations while allowing for expansion.
A new study suggests that advanced MRI scans can diagnose multiple sclerosis more quickly and accurately than traditional methods. The technology uses sophisticated imaging to detect white matter abnormalities in the brain, providing doctors with definitive evidence of injuries over time.
A long-term study found that patients with leukoaraiosis, a condition characterized by scattered loss of white matter in the brain, were 1.5 times more likely to have a stroke than those without the condition. The risk was even higher for multiple strokes, leading to increased disability.
Researchers used MR imaging to compare Alzheimer's patients' brains with those of children and adults, finding similar water molecule diffusion. The technique may help detect white matter disease earlier in dementia.
A study published in Biochemistry found significant alterations in white matter tissue of Alzheimer's patients, suggesting a potential initiating step for the disease. White matter degeneration may be caused by a disease of oligodendrocytes, leading to axon damage and cognitive impairments.
A study found that prolonged abstinence from alcohol can lead to partial reversal of structural brain damage, particularly in the frontal lobes and cerebellum. This suggests that brain function can improve with abstinence, offering hope for recovering alcoholics.
A study of over 3,000 senior citizens found that some drinking among the elderly may fight age-related brain injuries like silent strokes and white matter disease, but any level of alcohol intake may shrink brain matter. Light drinkers had fewer white matter lesions than abstainers or heavy drinkers.
Researchers used Diffusion Tensor Imaging (DTI) to track water molecules in the brain, revealing damage to white matter that affects message transmission within neurons. The study links this damage to neurocognitive deficits in detoxified chronic alcoholics.
Lawrence Schulman proposes a new scientific spin on science fiction, suggesting the possibility of reverse arrow systems where broken eggs re-form and timeline runs backwards. He uses statistical computer modeling to show that such systems could exist in regions with dark matter.
A new study reveals that women have a higher proportion of gray matter to cranial volume than men, while men have more white matter and cerebrospinal fluid. This difference is associated with sex differences in cognitive performance, particularly in spatial tasks.
Physicists suggest MACHOs may be made of a weird kind of mirror matter generated in the big bang, with potential for mirror planets and organisms. This theory could explain the presence of invisible stars on the outskirts of our Galaxy.
Research suggests that people with E-4 variant of the apo gene are at high risk for developing Alzheimer's disease and vascular diseases. The study found significant differences in brain volume and white matter abnormalities between those with and without the gene variant, suggesting a link to silent strokes and cognitive decline.
A new Ohio University study reveals that the political makeup of Congress and the party affiliation of the president play a significant role in shaping Supreme Court justices' rulings in criminal cases. The research found that liberal decisions by the court mirrored Democrats' influence, while conservative decisions were more prevalent...
