Synaptic pruning is a natural process that occurs in the brain between early childhood and adulthood. Your child’s brain was full of more than 100 billion neurons at birth. If the plant is a fruit tree, the fruit will be larger than the year before and taste better. Don’t we need every one of our neurons and synapses? While researchers once thought the brain only pruned synapses until early adolescence, recent advancements have discovered a second pruning period during late adolescence. During the second year of life, the number of synapses drops dramatically. Is a Weighted Blanket Helpful for Autism? When you trim your trees, you get all these benefits! If you’ve ever been a gardener or taken care of your own bushes and trees, you already know that regular pruning or cutting and trimming them only helps their growth. Synaptic pruning happens very quickly between ages 2 and 10. Constant stimulation causes synapses to grow and become permanent. If these synapses and axons are pruned out of his brain and he’s been replacing them with new skills developed by using the Fast ForWord™ program, then the synapses and axons will soon be completely gone. These plans provide the same coverage as…. This process is called apoptosis. During this time, about 50 percent of the extra synapses are eliminated. Pruning is one of best things you can do for your trees. Does synaptic pruning explain the onset of schizophrenia? Your child’s brain was full of more than 100 billion neurons at birth. The word prune is a verb which means to cut down some parts – usually the excess branches of a tree or plant in order to make it grow better. As more is learned about synaptic pruning, many researchers are also wondering if there is a link between synaptic pruning and the onset of certain disorders, including schizophrenia and autism. Thanks for writing this! Heredity is a major factor in heart disease. Where is research on synaptic pruning headed? Your email address will not be published. This article takes a look at what pruning is and the importance of pruning plants (trees and shrubs). Here's a timeline for what to expect. Synaptic pruning can be a good thing because some of the associations a child has for how the world works become more complex as he grows older. Theoretically, then, this under-pruning leads to an oversupply of synapses in some parts of the brain. In other words, the process follows the “use it or lose it” principle: Synapses that are more active are strengthened, and synapses that are less active are weakened and ultimately pruned. When it occurs in the brain, it makes the synapses more efficient. Synaptic pruning is a process that occurs inside the brain that results in reducing the overall number of neurons and synapses. While this is still a long way off, synaptic pruning may represent an interesting target for treatments for people with mental disorders. As your little one starts to explore and show interest in the world, they can play in different ways. Synapses are brain structures that allows the neurons to transmit an electrical or chemical signal to another neuron. Synaptic pruning is actually something that happens in all mammals, not just humans. If your child has auditory processing disorder that has been affecting his reading, his brain has already developed neural circuitry that isn’t serving him well. A few decades ago, people believed that once the brain was formed, that was it. By the time he or she is an adult, that number will reach 500 billion neurons. Surprisingly, a baby is born with even more, a lot more. Pruning in the brain is also called axon pruning or neuronal pruning. The timing of synaptic pruning varies by brain region. In the prefrontal cortex, peak levels of synapses occur sometime during the first year of life.
