1. Computer readable apparatus comprising a non-transitory storage medium, said non-transitory storage medium comprising a plurality of instructions to implement adjustment of a weight of a connection of a spiking neuronal network, the instructions configured to, when executed: increase the weight based at least on a response generated by at least one neuron of the network prior to receipt of an input signal; and reduce said weight based on said input signal preceding said response; wherein said connection is configured to communicate said input signal to said at least one neuron; the input signal is configured to convey information related to a context, the context comprising a feedback provided by another neuron of the network; and wherein said reduction and said increase of said connection weight cooperate to effect control of context-based response generation by said at least one neuron.
