- any group of neurons that conduct impulses in a coordinated manner, as the assemblages of brain cells that record a visual stimulus.
- a hardware or software system in which weighted connections between data nodes are refined to produce increasingly accurate results in information processing, as in pattern recognition or problem solving, with the goal of algorithmic computing that requires minimal human intervention.
- an interconnected system of neurons, as in the brain or other parts of the nervous system
- an analogous network of electronic components, esp one in a computer designed to mimic the operation of the human brain
