This STDP curve can be any combination of two exponential curves. The parameters (_alphaPlus,_tauPlus) specifies the exponential STDP curve at the pre-post side (i.e., a pre-synaptic neuron fires before a post-synaptic neuron). the parameters (_alphaMinus,_tauMinus) specifies the exponential STDP curve at the post-pre side. _tauPlus and _tauMinus must be positive number while _alphaPlus and _alphaMinus can be positive or negative according to users' needs. A positive value of _alphaPlus or _alphaMinus will increase the strength of a synapse (no matter a synapse is excitatory or inhibitory). In contrast, a negative value will decrease the strength of a synapse.
