Groups of neurons that are chemically linked or functionally related make up a biological neural network. A single neuron may have numerous connections to other neurons, and a network's total number of neurons and connections may be substantial. Although symptomatology synapses and other connections are possible, axons and dendrites often link at synapses. Diffusion of neurotransmitters results in additional types of messaging besides electrical messaging. A neural network is a computer programme that operates the way the brain's typical neural networks function. Such fictitious neural networks aim to carry out intellectual tasks like AI and problem-solving.
Information processing paradigms like Artificial intelligence, cognitive modelling, and neural networks are influenced by how biological neural systems process data. Cognitive modelling and Artificial intelligence make an effort to mimic some characteristics of biological neural networks. Artificial neural networks have been effectively used in the field of Artificial intelligence to create software agents (in computer and video games) or autonomous robots by performing voice recognition, picture analysis, and adaptive control.
