Mapping connections in a neuronal network

Mapping connections in a neuronal network

Researchers have mapped and catalogued more than 70,000 synaptic connections from about 2,000 rat neurons, using a silicon chip capable of recording small yet telltale synaptic signals from a large number of neurons. The research is a major advance in neuronal recording and may help bring scientists a step closer to drawing a detailed synaptic connection map of the brain.

Exploring the Connectivity of Neuronal Networks

Harvard University has made a groundbreaking advancement in the field of neuroscience by successfully mapping and cataloguing over 70,000 synaptic connections among approximately 2,000 rat neurons. This remarkable feat was achieved using a state-of-the-art silicon chip equipped with an innovative microhole electrode array capable of recording intricately woven signals emitted by numerous neurons simultaneously. This new technology represents a s…
