The video discusses the process of neurogenesis, or the brain's ability to repair itself and produce new neurons, in adults. Neurosurgeon Jass'lynn Blaj and her colleagues conducted experiments with brain tissue from patients with head injuries, discovering a new type of cell that behaved differently from stem cells and could potentially aid in brain repair. They found that these cells, called doublecortin-positive cells, were present in high concentrations near areas of brain damage, suggesting they could be a new source of cells capable of restoring the brain.
In experiments conducted on monkeys, the implantation of these cells into the brain resulted in a significant improvement in the animals' ability to recover from brain damage. This led to the discovery that these cells can be cryopreserved for later use in neuropathology, such as in the treatment of Parkinson’s disease.
The video also highlights the importance of lifestyle factors in controlling neurogenesis. It suggests that the production of new neurons increases with learning, sex, and physical activity, and is reduced by stress, lack of sleep, and a diet rich in saturated fats. It also emphasizes that the texture of food, the timing of meals, and the amount of food consumed can affect the production of new neurons.
In conclusion, the video emphasizes the importance of taking care of the brain through healthy lifestyle choices and encourages viewers to support further research into the potential therapeutic uses of neurogenesis.
1. The brain can repair itself with help, a process known as neurogenesis.
2. Adults can grow new neurons, a phenomenon called neurogenesis.
3. Neurosurgeon Jass'lynn Blaj and her colleagues discovered this process.
4. This process is beneficial for improving mood, enhancing memory, and preventing the aging process.
5. Jass'lynn Blaj was a resident physician in the emergency room of a traumatology department when she started studying the brain's repair process.
6. Jean-François Brunet, a biologist, decided to study pieces of brain to grow cells from them.
7. They found immature cells, similar to stem cells, present in the adult brain.
8. These immature cells can turn into cells of various organs and tissues.
9. The cells they discovered are different from stem cells as they divide slowly and die after a few weeks of cultivation.
10. These new type of cells are similar to stem cells but behave differently.
11. The cells came from 7 and red cells called doublecortin-positive cells.
12. These cells make up four percent of the cells in the cerebral cortex and are present when we were in the womb.
13. Scientists suggest that these cells may be involved in brain repair.
14. These cells are found in high concentrations near brain damage, indicating they could be a potential new source of cells capable of restoring the brain.
15. Roslin Bosch and colleagues conducted experiments on monkeys to find out whether these cells help animals recover from brain damage.
16. The monkeys were taught to take a test of manual dexterity and then had parts of the cerebral cortex responsible for hand movements damaged.
17. After a stroke, the monkeys recovered to a certain level due to the flexibility of the brain.
18. Scientists then implanted the same cells into the monkey’s brain.
19. The monkey recovered itself after the implantation of the cells two months later.
20. Neuroscientist Sandrine Thure states that new nerve cells appear in adults, a process called neurogenesis.
21. Every day, 700 new neurons are produced in the hippocampus.
22. By the age of 50, all the neurons we have from birth are replaced by neurons formed in the adult brain.
23. New neurons are important for learning, memory, and depression.
24. Taking antidepressants increases the production of new neurons and reduces the symptoms of depression.
25. Blocking neurogenesis decreases the effectiveness of antidepressants.
26. The production of new neurons increases with learning, sex, and reduces with stress and lack of sleep.
27. A study by Growing Gage from the Salk Institute found that the production of new neurons increases with calorie restriction, short-term fasting, and consumption of flavonoids, omega 3 fatty acids, and resveratrol.
28. The texture of food also affects the production of neurons; soft foods weaken the process of neurogenesis while crunchy and chewy foods are beneficial.
29. The timing of meals, the amount of food, and the type of food also affect neurogenesis.
30. Training, sex, healthy sleep, and physical activity also benefit the brain.
31. The brain will benefit from these factors if taken care of properly.
