Synaptic pruning, a phase in the development of the nervous system, is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans. [1] Pruning starts near the time of birth and continues into the late-20s. [2]

Synaptic pruning mechanisms play a large role in this process. Just as pruning or removing fruit from a tree can, in the end, help the tree be more effective and produce more fruit, removing synapses will make the brain more effective as well. This diagram shows the currently hypothesized role of astrocytes and microglia in synaptic pruning ...

Taken together, we identified two types of synaptic maturation events pruning events that coincide with sexual maturation and dimorphic prepatterning events that precede sexual maturation ...

Distance dependent pruning (DP) filters synapses based on the distance to the soma on the postsynaptic neuron. A fraction f1 of all synapses is removed. The soft max (SM) synapse filter...

Starting from birth until adolescence, the synaptic pruning process, preceded by synaptic overgrowth, optimizes the neurological network by removing redundant and weak connections as defined...

Synaptic Pruning Process: Analogous to sculpting, selectively trims synapses, relying on mechanisms such as apoptosis and neurotrophic factors for optimal neural function. Why Synaptic Pruning is Important: Essential for cognitive development, learning, and memory consolidation, preventing brain overload from excessive connections.

2023年5月9日 · In psychology, synaptic pruning refers to the process of eliminating weaker neural connections to strengthen existing ones during brain development. Synaptic pruning contributes to the refinement of neural architecture and plays a critical role in the efficient transfer of information.
