“The brain scans showed that ketone concentrations increased in the brain (including the tumor tissue) and correlated with ketone levels in the urine. These findings demonstrate that a ketogenic diet is safe for people with astrocytoma and may be beneficial as adjunctive therapy.”

“In addition, the microglia in several regions of the brain exhibited a clustering pattern around the amyloid plaques that facilitated clearance. These findings suggest that non-invasive techniques that promote gamma wave activity in the brain may be useful in treating people with Alzheimer's disease.”

“The study found that the holes where the arteries supplying the brain passed through have gradually increased from ancient fossil skulls to modern humans.”

“The anterior cingulate has been linked to superior cognition in late life." > Exercisers who improved their memory performance also showed greater increase in brain blood flow to the hippocampus, the key brain region affected by Alzheimer's disease.”

“The researchers also found shortened survival after castration when bladder cancer and melanoma cells were placed in the brain. Blocking androgen signaling with a drug shortened survival in male mice with glioblastoma cells placed in the brain, from 19 days to 17.5 days.”

“A recent study suggests that obesity impairs brain neuroplasticity. Neuroplasticity, the brain's capacity to reorganize itself in response to changes in its environment, is critical during periods of learning, psychological stress, and trauma.”

“FTA: > Scientists from Australia and France have shown that electromagnetic stimulation can alter brain organization, which may make your brain work better. In a new study, the researchers demonstrated that weak sequential electromagnetic pulses (repetitive transcranial magnetic stimulation -- or rTMS) on mice can shift abnormal neural connections to more normal locations.”

“When recall was successful, alpha and beta brain waves dropped shortly after the cue, a pattern often interpreted as reflecting information processing. These brain waves were also rhythmically modulated by breathing, with additional drops occurring at specific phases of the breathing cycle.”

“To fight the formation of these fibrils, however, a molecule would have to cross the blood-brain barrier -- a series of cell junctions that prevent certain substances from entering the brain.”

“Participants underwent repeated brain scans using magnetic resonance imaging (MRI) and positron emission tomography (PET). MRI was used to measure white matter hyperintensities (WMH), bright spots on brain images that usually reflect damage to small blood vessels.”
