Hidden Potential: What “Silent Synapses” Teach Us About a Child’s Brain
A fascinating new study from MIT reveals that the brain—far from having no more growth after early childhood—is actually filled with millions of “silent synapses,” or dormant neural connections waiting to be activated. These connections make up roughly 30% of synapses in the adult cortex and can quickly “turn on” when new learning occurs, allowing the brain to form new abilities. This discovery breaks from the ages old concept that once your brain forms, you can never get new brain cells again, since the brain actually maintains a reserve capacity for growth and adaptation throughout life. In simple terms, the brain is always ready to learn—it just needs the right input and stimulation to bring these hidden connections online.
This concept is especially powerful when we think about children. The developing brain is already primed for change, but MIT’s research suggests that even unused or underdeveloped pathways may still be waiting for the right signal to activate. That’s where gentle pediatric chiropractic comes in! Neuroplasticity—the brain’s ability to reorganize and form new connections in response to experience—is the foundation of learning, behavior, and development. When a child is exposed to healthy sensory input (like a pediatric chiropractic adjustment), movement (like neurologically-based exercises), and environmental engagement, these experiences can strengthen neural pathways and awaken those “silent” circuits. Conversely, if stress, dysfunction, or lack of proper input is present, some of these pathways may remain inactive, potentially contributing to challenges with focus, coordination, or regulation.
Here is how pediatric chiropractic care can play a supportive role. Gentle, neurologically-focused chiropractic adjustments aim to improve communication between the brain and body, creating a more balanced and responsive nervous system. Chiropractic adjustments combined with neurologically based exercises are new, novel inputs which essentially clears the brain of its ‘cobwebs’ When the spine and nervous system are functioning optimally, the brain is better able to receive, process, and adapt to sensory input—essentially giving those silent synapses the opportunity to activate. Chiropractic care may help remove interference so that the child’s natural neuroplasticity can be expressed more fully. For parents, this is an encouraging reminder: your child’s brain is not stuck or limited—it is adaptive, dynamic, and filled with untapped potential, just waiting for the right inputs to thrive.
A minimally speaking child with Autism started in our office 3 weeks ago. He is now pointing at letters on a letterboard, has more eye contact, is calmer both in school and at home, and even came to the office the other day and greeted me with a wave and said, “Hi Dr Rubin.” Neuroplasticity-- through chiropractic and neuro exercises-- added new inputs and changed the way this child’s nerve system is regulated--- and that is the true power of pediatric chiropractic!
