Aging Brain More Vulnerable to Even Mild Oxygen Deprivation

New research shows that even mild, prolonged exposure to low oxygen levels can significantly disrupt the blood-brain barrier (BBB) in aging brains. Using mice aged 2 to 23 months, scientists found that older mice experienced 4–6 times more BBB breakdown than younger mice under similar hypoxic conditions.

Eye Pressure May Trigger Irreversible Vision Loss

New research reveals how elevated eye pressure distorts blood vessels and disrupts oxygen delivery, potentially accelerating the progression of glaucoma, a leading cause of irreversible vision loss. Using advanced 3D modeling and fluorescent dyes, scientists found that even mild increases in eye pressure can restrict blood flow in the optic nerve region.

Brain-doping produced by your own body

Cognitive challenges trigger a slight oxygen deficit in hippocampal pyramidal neurons. This increases the production of erythropoietin (Epo) and its receptors in the active neurons, stimulating neighboring precursor cells to form new neurons and enhancing connectivity.
