Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Neural plasticity and neural regeneration are the same thing. | Neural plasticity and neural regeneration are two different processes in neuroscience. Neural plasticity refers to the brain’s ability to change its structure and function in response to experiences, while neural regeneration is the process of regrowing damaged or lost neurons. |
| The brain cannot regenerate new neurons after injury or damage. | While it was previously believed that the adult brain could not generate new neurons, recent research has shown that neurogenesis (the growth of new neurons) can occur in certain regions of the adult brain, such as the hippocampus. However, this process is limited and does not occur throughout all areas of the brain. |
| Once a neuron dies, it cannot be replaced by a new one through any means. | While it is true that some types of neurons do not regenerate once they die, there are other types of cells in the nervous system (such as glial cells) that can differentiate into functional neurons under certain conditions. |
| Neuroplasticity only occurs during childhood development; adults cannot experience significant changes in their brains’ structures or functions over time. | Neuroplasticity continues throughout an individual‘s lifespan; however, its extent may vary depending on factors such as age and environmental stimuli. |
| Brain training games/apps can significantly improve cognitive abilities by increasing neuroplasticity/regeneration. | While engaging in mentally stimulating activities may promote neuroplasticity/regeneration to some degree, there is currently no conclusive evidence suggesting that these activities alone lead to significant improvements in cognitive abilities beyond specific tasks related to those activities. |
