This shows a brain and a virus.Researchers discovered a connection between Alzheimer’s disease and herpes simplex virus-1 (HSV-1), suggesting viral infections may contribute to neurodegeneration. The study found that tau protein, typically seen as harmful in Alzheimer’s, might initially protect the brain from the virus but later exacerbate damage.

This shows the developing eye.Researchers uncovered that the vestibulo-ocular reflex, a vital brain circuit stabilizing gaze during body tilts, matures independently of sensory input in newborns. This reflex, essential for perceiving a stable environment, enables the eyes to counter-rotate with body movements.

This shows a clock and a person.Time perception varies depending on context, often slowing in emergencies or unfamiliar settings and speeding up during absorption or as we age. Time expansion experiences (Tees) occur when seconds stretch into minutes, frequently in accidents, sports, or moments of calm.

This shows a brain.While humans share over 95% of their genome with chimpanzees, our brains are far more complex due to differences in gene expression. Research shows that human brain cells, particularly glial cells, exhibit higher levels of upregulated genes, enhancing neural plasticity and development.
