From The Collaborative International Dictionary of English v.0.48 :

  Neuron \Neu"ron\, n.; pl. Neura. [NL., from Gr. ney^ron
     nerve.] (Anat.)
     1. The brain and spinal cord; the cerebro-spinal axis;
        myelencephalon. [obsolete] --B. G. Wilder.
        [1913 Webster]
  
     2. (Cell Biology) The characteristic specialized cell that is
        part of the nervous system, serving to conduct electrical
        impulses to and from the brain, and also between other
        parts of the body, and composed of a main cell body, the
        axon, with a varying number of processes of varying
        length, the dendrites; a nerve cell. The movement and
        behavior of higher animals depends on the signals
        tranmsitted by such nerve cells.

      (ANN, commonly just "neural network"
     or "neural net") A network of many very simple processors
     ("units" or "neurons"), each possibly having a (small amount
     of) local memory.  The units are connected by unidirectional
     communication channels ("connections"), which carry numeric
     (as opposed to symbolic) data.  The units operate only on
     their local data and on the inputs they receive via the
     connections.
  
     A neural network is a processing device, either an
     algorithm, or actual hardware, whose design was inspired by
     the design and functioning of animal brains and components
     thereof.
  
     Most neural networks have some sort of "training" rule whereby
     the weights of connections are adjusted on the basis of
     presented patterns.  In other words, neural networks "learn"
     from examples, just like children learn to recognise dogs from
     examples of dogs, and exhibit some structural capability for
     generalisation.
  
     Neurons are often elementary non-linear signal processors (in
     the limit they are simple threshold discriminators).  Another
     feature of NNs which distinguishes them from other computing
     devices is a high degree of interconnection which allows a
     high degree of parallelism.  Further, there is no idle memory
     containing data and programs, but rather each neuron is
     pre-programmed and continuously active.
  
     The term "neural net" should logically, but in common usage
     never does, also include biological neural networks, whose
     elementary structures are far more complicated than the
     mathematical models used for ANNs.
