The brain has the ability to modify the contacts between neurons. Among other things, that is how it prevents brain activity from getting out of control. Researchers from the University Hospital Bonn, together with a team from Australia, have identified a mechanism that plays an important role in this. In cultured cells, this mechanism alters the synaptic coupling of neurons and thus stimulus transmission and processing. If it is disrupted, disorders such as epilepsy, schizophrenia or autism may be the result. The findings are published in the journal Cell Reports.
Almost 100 billion nerve cells perform their service in the human brain. Each of these has an average of 1,000 contacts with other neurons. At these so-called synapses, information is passed on between the nerve cells.
However, synapses are much more than simple wiring. This can already be seen in their structure: They…
