Receptive field estimation using the STA approach. (A) White noise image sequence with spiking activity superimposed as red dots. (B) 3D volume visualization of the receptive field of one neuron. (C) Temporal slices of the receptive field (RF(·, ·, z)). Slices are in increasing time order from top to bottom and left to right. Time period between two slices is 33 ms. (D) Temporal profile passing through the peak activity location of the spatio-temporal volume (RF(x_M, y_M, ·) where (x_M, y_M, z_M) = argmax_{x, y, z}RF(x, y, z)).
