By studying rodents, researchers showed that instead of attacking germs, some neutrophils may help heal the brain after an intracerebral hemorrhage, a form of stroke caused by ruptured blood vessels. The study suggests that two neutrophil-related proteins may play critical roles in protecting the brain from stroke-induced damage and could be used as treatments for intracerebral hemorrhage.
The growth of certain aggressive brain tumors can be halted by cutting off their access to a signaling molecule produced by the brain’s nerve cells, according to a new study.
By reprogramming skin cells into nerve cells, researchers are creating cell models of the human brain. In a new study, the researchers describe how cells from patients with the severe developmental disease lissencephaly differ from healthy cells. The method can provide vital new knowledge on difficult-to-study congenital diseases.
The human and non-human primate brain is remarkable in recognizing partially hidden objects. A study, conducted during a shape recognition task, shows as more of the shape is hidden, a brain area involved in cognition starts to sends signals to the visual cortex. The findings make the scientists wonder if this communication between different brain areas might be impaired in people with autism or Alzheimer’s. Both conditions can cause confusion in cluttered surroundings and problems recognizing objects.
Scientists say a new study indicates that the excessive burst of new brain cells after a traumatic head injury that researchers have traditionally believed helped in recovery could instead lead to epileptic seizures and long-term cognitive decline.
Increased communication between distant brain regions helps older adults compensate for the negative aspects of aging, reports a new study.
Thirdhand-smoke results when exhaled smoke and smoke emanating from the tip of burning cigarettes gets on surfaces such as clothing, hair, homes, and cars. Using a mouse model, researchers have found that thirdhand-smoke exposure has a significant effect on health, specifically the liver and brain, as early as one month after initiation of exposure — an effect that worsens with time.
Researchers have confirmed that abnormalities in a common brain chemical are linked to sudden infant death syndrome (SIDS).
Researchers have studied the brain activity of young binge-drinking college students in Spain, and found distinctive changes in brain activity, which may indicate delayed brain development and be an early sign of brain damage. The results suggest that bingeing has tangible effects on the young brain, comparable with some of those seen in chronic alcoholics.
Medical researchers have demonstrated that the protein tyrosine phosphatase receptor type J (PTPRJ) inhibits leptin signaling and that induction of PTPRJ in the hypothalamus is a cause of leptin resistance.
