Final answer:
Increased neurogenesis is associated with improvements in cognitive function, emotional regulation, motor coordination, and visual perception. However, stress has a negative impact on neurogenesis and emotional regulation.
Step-by-step explanation:
Increased neurogenesis, the birth of new neurons, is associated with improvements in:
- Cognitive function: Neurogenesis in the hippocampus is correlated with how well rats learn new tasks.
- Emotional regulation: Some antidepressant medications promote neurogenesis in the hippocampus, which can enhance emotional regulation.
- Motor coordination: While there is not direct evidence linking neurogenesis to motor coordination, it is possible that increased neuron growth may lead to improved motor skills.
- Visual perception: There is limited research on the direct relationship between neurogenesis and visual perception, but neurogenesis may play a role in brain processes related to vision.
However, drawbacks are observed in emotional regulation as well. Stress has been found to have a negative impact on neurogenesis, which can in turn affect emotional regulation.
