Which Of The Following Is Not True About Brain Neuroplasticity?
The human brain has an amazing ability to change and adapt in response to experience. This process, known as neuroplasticity, is thought to underlie our capacity to learn and remember. Neuroplasticity occurs at all levels of the brain organization, from individual neurons to large-scale cortical networks.
There are several myths about neuroplasticity that circulate the internet and are often perpetuated by well-meaning but misguided people. Let take a look at some of these myths and see why they’re not true.
Myth #1: You can only grow new brain cells during childhood. Truth: Although the brain typically reaches its maximum size in early adulthood, it is still capable of growing new neurons (a process known as neurogenesis) throughout life. In fact, there is evidence that neurogenesis occurs in certain areas of the brain in response to learning new information or acquiring new skills.
Myth #2: Once you lose neurons, you can never get them back. Truth: Although it is true that neurons cannot be regenerated once they die, the brain has a remarkable ability to compensate for lost or damaged cells. When faced with injury or disease, the brain can reorganize itself and reroute connections to circumvent the damaged area. This process is known as neuronal plasticity or neural rewiring.
Myth #3: The aging brain is inevitable decline. Truth: It is true that some cognitive functions, such as memory and processing speed, tend to decline with age. However, there is evidence that the aging brain remains quite plastic and capable of change. In fact, older adults who engage in mentally stimulating activities, such as reading, puzzles, and social interactions, tend to have a slower rate of cognitive decline than those who don’t.
Myth #4: brains are hardwired and unchanging. Truth: The human brain is an incredibly complex and dynamic organ, constantly changing in response to experience. Even in adulthood, the brain continues to grow new neurons and form new connections between cells. This flexibility allows us to learn new skills, remember experiences, and adapt to our ever-changing environment.
