Human can identify a person through thoughts.which means humans neurons are getting trained itself. Therefore through Artificial Neural Network we can train artificial neurons using computer programming . using neural network we are trying to build a network between neurons to transfer the electrical signals.which are consists of neural commands . 
usually Computer response time is 10^6 times faster than humans response time because of the silicon Integrated chips.
silicon chip response time :- 1 nanosecond
human response time :- 1 millisecond
but human can perform faster than chips because human has massively parallel neural structure. If we consider human neuron structure it has synaptic terminals, cell body(neurons), basal dendrite and axon. Each components has some function to transfer signal to neurons.
Also we can map Human neurons with Artificial neurons as bellow...
Also we can map Human neurons with Artificial neurons as bellow...
| Human neurons | Artificial neurons |
| Neurons | Neurons |
| Axon | Wkj (weight) |
| Synaptic terminals to next neuron | output terminals |
Synaptic terminals taking input | input terminals (Xj) |
