Strategy Developed to Improve Delivery of Medicines to the Brain

The experimental treatment method allows small therapeutic agents to safely cross the blood-brain barrier in laboratory rats by turning off P-glycoprotein, one of the main gatekeepers preventing medicinal drugs from reaching their intended targets in the brain.

Math Ability Requires Crosstalk in the Brain

A new study finds strength of communication between the left and right brain hemispheres predicts performance on basic arithmetic problems. Findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia - an inability to understand and manipulate numbers.

Survival Statistics Show Hard Fight When Malignant Brain Tumors Appear at Multiple Sites

When aggressive, malignant tumors appear in more than one location in the brain, patient survival tends to be significantly shorter than when the disease starts as a single tumor, even though patients in both groups undergo virtually identical treatments, according to research at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Research Institute.

The Roots of Human Self-Awareness

Neuroscientists have believed that three brain regions are critical for self-awareness: the insular cortex, the anterior cingulate cortex, and the medial prefrontal cortex. Patient R is helping a research team show that self-awareness is more a product of a diffuse patchwork of pathways in the brain—including other regions—rather than confined to specific areas.

Nanoparticles Reboot Blood Flow in Brain

New research would help emergency care workers and battlefield medics stabilize blood flow in the brains of traumatic injury victims. Researchers developed a nanoparticle-based antioxidant that quickly quenches free radicals that interfere with regulation of the brain’s vascular system.

New Research Determines How a Single Brain Trauma May Lead to Alzheimer’s Disease

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer’s disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer’s. The paper, published in The Journal of Neuroscience, identifies the complex mechanisms that result in a rapid and robust post-injury elevation of the enzyme, BACE1, in the brain. These results may lead to the development of a drug treatment that targets this mechanism to slow the progression of Alzheimer’s disease.
