Synaptic pruning is the process in which the brain removes neurons and synapses that it does not need. This usually takes place when a person is 2–10 years old. The brain contains millions of neurons ...

Synaptic pruning is a crucial neurodevelopmental process through which the brain refines its neural circuitry by systematically eliminating excess or weak synaptic connections. During early childhood ...

Synaptic pruning is a little like sleep. We know both processes are important to healthy brain function, but we don't know exactly how they happen, nor how to reliably treat problems in the system.

Kanazawa, Japan - Artificial neural networks are machine learning systems that are composed of a large number of connected nodes called artificial neurons. Similar to the neurons in a biological brain ...

A multidisciplinary team of scientists has discovered the mechanism that controls synaptic pruning of new neurons in the adult brain. The team discovered that microglial cells control the number of ...

In the Alzheimer’s disease brain, synaptic loss correlates with cognitive decline, and is considered a sign of disease progression. But is synaptic loss always bad? Provocative new data from several ...

An analysis of how synaptic proteins change during early development reveals differences between mice and marmosets but also what's different in individuals with autism spectrum disorders. The ...

In the last five years, neuronal pentraxins have emerged as potential markers of synaptic loss. In the case of NPTX2, researchers may now be able to explain why. In the March 29 Science Translational ...
