[Nonspecific brain structures and specialization in the central nervous system].
It has been demonstrated that corticofugal influences may exert selective control of single sensory signals which converge on the neurons of the striatum and other non-specific structures of the brain. This finding suggests that complex sensory image may be formed not by assembling separate elementary signals, but rather by a selective control of these signals into a total sensory inflow within the network brain structures. This conclusion is confirmed by comparative anatomical data. In the phylogenesis of vertebrates, brain structures differentiate presumably into both the specific ones which perform the analysis of only the given kind of information, and those (conventionally described as non-specific) which are specialized on sensory integration and exhibit functional polymodality.
