Looking for burst signals

One of the most visible features of a functional Biological Neural Network (BNN) is its ability to generate synchronized spikes or burst signals, similar to those observed in living mammal brains.  Once they have reached a sufficient development stage, in particular in terms of connectivity, in vitro neuronal cultures tend to exhibit spontaneous bursts of …

Diversity of biological neural network cultures

The core component of  a Biological Neural Network (BNN) unit is the biological culture of neural cells. There are two main approaches to setup a BNN culture: extracting neurons at early development stage from non-human brains, for instance cortical neurons from postnatal rat brain, or differentiating stem cells such as human induced pluripotent stem cells …
