The human brain is capable of some remarkable feats—it performs very complex information processing. The neurons that make up our brains are very densely connected and perform in parallel with others. These biological neurons receive and pass signals to other neurons through the connections (synapses) between them. These synapses have strengths associated with them and increasing or weakening the strength of the connections between neurons is what facilitates our learning and allows us to continuously learn and adapt to the dynamic environments we live in.
As we know, the brain consists of neurons—in fact, according to recent studies, it is estimated that the human brain contains roughly 86 billion neurons. That is a lot of neurons and a whole lot more connections. A very large number of these neurons are used simultaneously...
