title: Brain's entropy partitions.
abstract: Since the brain processings can be expressed by ballistic or ramp systems, the brain entropy is herein analysed in respect to the distributions of the internal ((MS)1) and external messages ((ME)E) conveyed through the sensory systems. In such a context, it is shown that a first partition (through a primary folding) is established between the neural systems involved in the processings related with the external (RSE) and internal (BSI) environments. Indeed, secondary foldings in both RSE and BSI due to non-homogeneities in (MS)E and (MS)1 are discussed. Finally, the results are extended to the neural phenomena during the brain's embriogenic growth.
