The increase in synaptic density continues throughout much of the first year of life. However, around 1 year of age up until 10 years of age, the number of synapses in the brain begins to decrease through a process called synaptic pruning (e., Huttenlocher, 1994). Why would the brain ever undergo a decrease in synapses? WebbThese extra connections actually hinder brain function. The result of this period of blooming and pruning is a brain – or a rosebush – that is healthy and thriving. Throughout development, there are multiple periods of blooming and pruning. These bursts occur at different times and in different regions across the brain. east baton rouge assessor search
