The spiking of a single neuron may be measured by a microelectrode,and its sequence of spikes over time is called a spike train. A simple and commonly-usedstatistical model for a spike train is an inhomogeneous Poisson point process, which hasthe following property: Forntime windows of length , lettingYidenote the number ofspikes generated by the neuron in theithtime window, the random variablesY1,..,Ynareindependent and distributed asYi Poisson ( i ), where the parameter icontrols thespiking rate in theithtime window.
