Children with autism have extra synapses in brain

Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain "pruning" process during development, according to a study by neuroscientists at Columbia ...

Connecting neurons to fix the brain

Each of the brain's 100 billion neurons forms thousands of connections with other neurons. These connections, known as synapses, allow cells to rapidly share information, coordinate their activities, and achieve learning ...

Chemical synapse

Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits within the central nervous system. They are crucial to the biological computations that underlie perception and thought. They allow the nervous system to connect to and control other systems of the body.

The adult human brain is estimated to contain from 1014 to 5 × 1014 (100-500 trillion) synapses.[citation needed] Each mm3 of cerebral cortex contains roughly a billion of them.

The word "synapse" comes from "synaptein", which Sir Charles Scott Sherrington and colleagues coined from the Greek "syn-" ("together") and "haptein" ("to clasp"). Chemical synapses are not the only type of biological synapse: electrical and immunological synapses also exist. Without a qualifier, however, "synapse" commonly means chemical synapse.
