The following videos demonstrate a computation model of primary somatosensory cortex undergoing self-organization. The model relies on Neural Field [1]. The complete mathematical/computational model as well as all the details and results are given in [2] and [3].

Self-organization of receptive fields (RFs)⌗

Evolution of a single RF during self-organization⌗

Evolution of multiple RFs during self-organization⌗
