The astounding complexity of human thoughts, feelings, and behavior is
generated by a self-organizing network of 10^11 neurons. What basic com-
putation is performed by each neuron in such a network? We propose to
model neuronal computation by online learning algorithms for estimation
and prediction of time varying signals. First, by using projection pursuit,
synaptic learning rules could discover a linear combination of inputs with
non-Gaussian, e.g. Laplace distribution. Second, Laplacian signal contami-
nated by Gaussian noise can be robustly estimated by an integrator followed
by a threshold linear response function common firing rate model of a neu-
ron. If the estimation signal must be encoded by a binary sequence, the
estimator reduces to an integrate-and-fire neuron
