- Neuroscientists have discovered newly formed neurons in adult human brains up to age 78, confirming adult neurogenesis.
- The study identified neural precursor cells in the hippocampus, which develop into new neurons.
- Evidence of neurogenesis was found in postmortem brains of individuals aged 13 to 78, except one.
- Two adults showed significantly more neural precursor cells and immature neurons, with one having epilepsy.
- The research suggests neurogenesis may occur in other brain regions, like the olfactory bulb, though unconfirmed in humans.
- Disrupted neurogenesis in mice is linked to Alzheimer’s and depression, hinting at potential human implications.
- The findings resolve the debate on adult neurogenesis, paving the way for studying its role in brain function and disorders.
