Older people can still produce brain cells even at 79, study says

The video discusses a study by scientists from the University of Columbia on neurogenesis, the process of producing new neurons, even in older adults. The study examined the brains of 28 deceased individuals aged 14 to 79 to determine if aging affects neuron production. Researchers found similar numbers of neuroprogenitor cells and immature neurons across all ages, leading to the conclusion that the human brain can produce neurons even in old age.

What is the process called where new neurons are produced daily, even in older individuals?

• Osmosis

• Metamorphosis

• Photosynthesis

• Neurogenesis

Which university's scientists conducted the study on neuron production in aging?

• MIT

• University of Columbia

• Harvard University

• Stanford University

How many individuals' brains were examined in the study?

• 14

• 28

• 79

• 100

What age range did the study participants fall into?

• 14 to 79

• 10 to 60

• 20 to 70

• 30 to 80

What did the researchers conclude about neuron production in the human brain?

• It decreases significantly with age.

• It only occurs in young individuals.

• It remains possible even in old age.

• It stops completely in old age.
