Reading Task 1. Read the passage. For questions 1-5, select the appropriate option A, B, C, or D. Can you imagine

embryonic cells transform into mature neurons that integrate into the existing neuronal network. However, once our brains reach maturity, the production of new neurons significantly decreases. This led scientists to believe that the brain has limited regenerative capacity.

Recent studies, however, have challenged this notion. Researchers have discovered that certain brain regions do possess the ability to generate new neurons even in adulthood. One such region is the hippocampus, which is responsible for learning and memory. Studies conducted on animals, such as mice, have shown that the hippocampus can generate new neurons throughout the lifespan.

Moreover, scientists have also explored the potential of stimulating neurogenesis, the process of generating new neurons, in other brain regions. They have found that physical exercise, environmental enrichment, and engaging in cognitively stimulating activities promote the production of new neurons in the adult brain.

The findings from these studies give hope that in the future, it might be possible to enhance the brain"s regenerative capacity. If scientists can unravel the mechanisms underlying neurogenesis and develop techniques to stimulate it, it may be feasible to repair damaged brain tissue and improve brain function.

In conclusion, while our brains currently have limited regenerative capacity, ongoing research shows promise for enhancing the brain"s ability to repair itself. The discovery of neurogenesis in adulthood and the identification of factors that promote it provide a foundation for further exploration. Although the idea of the brain regenerating itself may still seem like science fiction, ongoing advancements in neuroscience bring us closer to making it a reality.
