For this reason, gains are closely monitored. When . What is the Cephalocaudal principle of child development? It might be ongoing: While big neurological changes happen in childhood, emerging research in neurobiology indicates that dendrites and axons continue to change, adapt, and develop throughout the lifespan.

In senile dementia (average age, 76.0), dendritic trees were less extensive than in adult brains, largely because their terminal segments were fewer and shorter. Once the growth stops, they generate small specialized protrusions known as dendritic spines for nerve impulse transmission. And, even if new neurons do appear later in life, scientists dont know if they could integrate into long-established brain networks or affect cognition.
